Recommended Maximum Email Size and Proven Ways to Optimize It

Every email sending provider has its own maximum email size limit. However, there is no unique standard – limits are dictated mostly by performance and security reasons. There are many things you should keep in mind when preparing your email notifications or newsletters: from the maximum size of file attachments and HTML part to the email client your recipients will most likely use. Also, there are some not so obvious factors, which impact the actual email size and deliverability. In this article, we have gathered replies to the most common related questions:

  • What is the recommended size for the email body and attachments?
  • What are the limits of different email clients and sending providers?
  • How do the embedded images affect email size, spam score, and deliverability?
  • What are the common issues and errors related to email size and how to handle them?

Also, we have implemented an email size limit for Mailtrap: let’s review how it works and how it can help you with testing your email deliverability.

Types of email size limits

Email size limits are used for three main reasons:

  1. Performance. Email systems are not designed to transfer large volumes of data. They deal with SMTP, which is a quite outdated protocol. Most of the systems are not able to process multiple data sources at once. In addition, mail transfer agents often scan incoming data for viruses and other potential risks, which also takes resources and affects system performance.
  2. Database/storage size. Email data should be stored on a server (either cloud or local). This is why not only the message itself but also the inbox as a whole has its own limits.
  3. Security. Points 1 and 2 on our list also lead to potential security vulnerabilities. Email systems usually use a limited number of ports to retrieve data. This makes them candidates for DoS (denial of service) attacks: a huge amount of large messages can take the whole system down. This is also known as an email bomb.

When preparing either transactional or marketing emails, you should consider two limits:

  • limit to send a message (your email system)
  • limit to retrieve a message (your recipients’ mail system).

For example, if your email service is able to send messages up to 15 MB but the email recipient can retrieve messages only up to 10 MB, it’s obvious that your email should not exceed 10MB. Otherwise, the email will be rejected. It is useful to know the allowance for your recipient’s incoming messages.

If you work with a big database of email addresses to send transactional or marketing emails and don’t have such details about your recipients, you should follow a general rule: send messages that don’t exceed 10 MB.

Limits for popular email sending providers and clients like Gmail, Outlook, Sendgrid, etc.

You can see that most email clients are capable of retrieving 20 – 25 MB of email data. It’s a pretty rare situation when you need to send a mass email with large attachments. But it is still possible when you send numerous booking or order confirmations, for example. However, besides general deliverability, there are few more concerns related to sending large messages. Spam score and rendering issues are the most important. Moreover, some ESPs like Postmark have additional limits for the email body size.

What else should you consider about the size of your email?

Taking care to create a message that will be successfully delivered to your recipients, you should also think of which folder it will go to, how quickly it will be delivered, and how happy your recipients will be.

Spam score

Avoiding spam filters and targeting the main folder of your recipient’s inbox is one of the trickiest things in email handling. You won’t find strict and ubiquitous criteria for spam detection. However, there is a list of common “anti-spam” rules, and the size-related points are at the top of it.

Technically, there is no message body limit in the SMTP protocol. Still, some providers have their own limits. For example, Postmark allows the HTML and text parts each to be 5 MB, while Gmail clips the body of messages over 102 KB.

Many tests by various providers prove the correlation between email size and deliverability. In most cases, messages with a body over 100 – 150 KB trigger spam filters. So, the common recommendation is to keep email body size between 15 KB and 100 KB.

Rendering issues

Another aspect of large emails is their loading and/or rendering speed. Your recipients do not always have access to a high-speed connection, and a long-lasting message loading process might cause irritation. In addition, in many email clients, a large email body might be rendered just partially, and your recipient will see just parts of images or clipped content. This might strongly harm your customer digital experience and leave a bad general impression.

Notwithstanding the numerous limitations and hidden constraints, there are common rules on building well-performing emails. The first of these is to decrease and optimize email body size.

What does affect the email size and how can you optimize it?

Each element of the message and the way it’s implemented impacts email size.

  • Attachments. With attachments everything is straightforward. These are enclosed files and don’t affect the email body size. The total email limit usually includes all of the attachments. The best option is to upload files you need to transfer to the cloud and put a link into your message. Due to security issues, many file types are blocked or are considered dangerous (including .doc, .xls, and .pdf).
  • Images and other embedded elements. Even simple notifications usually contain images, at least your company logo. Their size depends on the image format and the way the image is embedded into the message. We had a closer look at this topic in this article. In short, wherever possible, link to an image hosted on an external server (in the HTML, so it will be displayed as part of the message).
  • Encoding. MIME-encoded (base64) messages add 33% to your email size. Keep this in mind when coding a multipart message.
  • Other. Every single message element affects its general size. Message headers, signatures, formatting – all of these add extra kilobytes.

Rules of a perfect email

Considering the above mentioned limits and dependencies, we have created a short email size optimization checklist. Here are the best practices for building a well-performing email in terms of size:

  1. Keep the email body from 15 KB to 100 KB.
  2. Don’t add attachments over 10 MB. If possible – upload your files to the external server and make them available online/ for download using a link.
  3. Don’t overuse images, GIFs, and other multimedia content.
  4. Remember that almost 42% of emails are opened on mobile devices. Keep this in mind when creating email templates. They should be responsive. Using a responsive email framework or an email builder can save you nerves and kilobytes.

Check email size in Mailtrap before sending

Even if you followed all recommendations and have crafted the perfect message, checking its size is not an easy task. Whether you are coding a message in your app or preparing a template to send via Gmail, you need to use a third-party tool, actually send your message, or download it then to explore its size.

If you use Mailtrap for testing your emails before sending them to your real recipients, you can easily check both the email body and attachment size.


 

As soon as your test message is trapped in your virtual inbox, the total email size is displayed along with the message headers. If your message has attachments, you will see a list of them with file names and sizes.

Also, Mailtrap has email size limits, which depend on your billing plan. You can test messages up to 5 MB (total email size with attachments) for free. The maximum possible email size to test is limited to 25 MB.

SMTP errors related to email size

Instead of offering a conclusion, let’s review the most common SMTP errors related to the mail size. There are two of them:

SMTP codes will be completed with additional numbers and messages so you will be able to understand the exact reason. The general rule is to keep your email size as compact as possible, check, and test it before sending to real recipients.

Secret Email System Review - Recommended or Not?

Matt Bacak’s secret email system is one of the most successful products in the WarriorPlus marketplace in recent memory. My secret email system review will not try to hard sell you on the product – I mean, it’s pretty cheap, so if you’re going to buy it, you’re going to buy it. Instead, I’ll concentrate on explaining the benefits of email marketing and how to get the most out of Matt’s system.

Nowadays, digital marketing is essential for every business. But what is the best strategy? There are many different points of view, but one thing is certain: emails are essential. Email marketing is one of the most efficient and cost-effective ways to promote a business online, and it is simple and inexpensive to get started. The most important thing is to understand your audience and deliver content and offers that are truly relevant to them.

The PDF Download of an Honest Secret Email System Review
The front-end product
What Matt Bacak is selling, which has been promoted by such capable affiliates as Curt Maly, is a PDF ebook that you can download immediately after purchasing. However, there are a number of bonuses included to sweeten the deal. You get access to Mr. Bacak’s private Facebook group, and instead of a simple PDF download, you get a massive zip file full of useful files and videos.
Now that we know what we’re up against, let’s get into this secret email system review!

What is Included in the Secret Email System Download?
Here is a list of everything you get inside the zip file sold at the front end of the Secret Email System:

Matt Bacak’s 3x Formula Calculator (plus a video explaining how to use it)
1000 email swipe files in text format (swipe files or “swipes” are like templates you can repurpose in a variety of ways).
A 1.5-hour video session

Free access to Matt’s high-converting leadpages lead generation template
A massive book of swipe files (in PDF format)
A copy of Matt’s book, Secrets of the Internet Millionaire Mind,
A video tutorial on how to select “irresistible offers” from affiliate marketplaces.

The PDF version of The Secret Email System
The Checklist for the Secret Email System PDF
Text files containing instructions for joining the Facebook group and other bonuses
Matt was charging less than $6 for all of that value last time I checked. He is demonstrating his many years of experience in internet marketing by creating an irresistible offer that people will want to buy and affiliates will want to promote. As a result, the Secret Email System has sold more copies on Warrior Plus than any other product in recent memory.

Examine everything included in the secret email system
Who is Matt Bacak, and why should I listen to him?
Many consider Matt Bacak to be an internet marketing legend, and email marketing is his primary focus. My first encounter with Matt came in the form of some Facebook ads he ran. Matt explained who he was in the video ad (which featured a little guy dancing in the background) and invited me to visit his blog, which I did. He demonstrated a thorough understanding of online business, so it’s no surprise that he put together the ultimate email marketing package.

Overall, Matt’s ad was one of the strangest Facebook ads I’ve ever seen. It was also one of the most effective and memorable. I didn’t buy whatever Matt was selling that day, but I read his blog and remembered his name and who he was. When I saw Curt Maly running ads for Matt Bacak’s Secret Email System months later, it made a big difference.

When I saw that the price was under $6 and that the bonuses were included, I knew I had to buy the product. I didn’t buy it right away because I was too busy, but it stayed in the back of my mind until I had the opportunity to do so.
If it isn’t obvious, I’ll explain: the reason you should listen to Matt Bacak is that he knows how to get inside people’s heads and stay there, both as a marketer and as a public figure.

Is the Secret Email System Training of Good Quality?
At first glance, the training does not appear to be groundbreaking, but this is because the creator is unconcerned about flashy packaging. You literally get a zip file full of stuff that most people would put on a membership website. I can see how this would irritate some people who are used to flashy ClickFunnels and Kajabi courses.

If that describes you, you’re missing out. Matt’s training isn’t flashy, but it describes a solid system that most businesses can implement in some way. As the name implies, it all revolves around building a list and emailing it on a regular basis. Did I ruin the surprise?
Front end offer and upsells from a secret email system
Bonuses from the Secret Email System (and a Bonus From Me)
I’ve already outlined everything you get in the zip file that serves as the funnel’s front-end offer. Everything else, other than the Secret Email System PDF itself, is considered a bonus, and the total value could easily be in the hundreds of dollars.

That’s why purchasing this product was such a no-brainer for me. I already knew how to write good marketing emails, but I really wanted to look inside Matt’s system.
In addition to everything else, you’ll get lifetime access to Matt’s private Facebook community. He answers questions from people here on a daily basis, and it can be a great place to learn.

The truth is that you get so much value and stuff from purchasing this product that adding another bonus is almost pointless. But I’m a bonus machine, so be prepared.
In 2020, I published my first book on email marketing, How to Build Your First Money Making Email List. You’re already getting a lot of reading material, but if you purchase Matt’s product through my link, I’ll add it to the stack. Most of the books I write sell for $27, so this just adds to the ridiculous valuation of this sub-six-dollar product.
Bonuses Bonuses for Matt Bacak’s Secret Email System
Will This Product Really Help You Make Money Online?

It all depends on whether or not you use the secret email system. According to multiple sources, Matt Bacak is in charge of millions of dollars in sales for both himself and his clients. And the best thing about this guy is that he’s upfront and honest, and he puts his money where his mouth is. What I mean is that he doesn’t hold anything back in the books he writes. That is another reason he has amassed such a large and devoted fan base.

Finally, if your business can profit from email marketing or if you want to use email marketing to become an influential public figure, I believe this ebook can assist you. It helped me improve my understanding of the business side of being an affiliate marketer and is far more valuable than the price tag. This product will be especially useful if you want to get started in affiliate marketing with a small investment.

Going Beyond My Review – Secret Email System
The book itself goes beyond email marketing, but I don’t want to give too much away. Instead, I’ll go over some of the finer points of lead generation quickly so you can get started building your email list as soon as possible.

Now, I’m guessing that roughly 90% of people reading this review are affiliate marketers or are interested in affiliate marketing. As a result, I’m going to focus on lead generation strategies used by many successful affiliates. If you want to learn more about my favorite affiliate marketing strategies, click on that link to read my in-depth guide.

The Most Effective Methods for Building an Email List
Here’s a rundown of some of the best (and quickest) ways to build an email list. First, you’ll need a way to collect emails, and it must be a high-converting method. My favorite lead generation tools are:
ConvertBox (on-site messaging software/advanced popup builder)
ConversioBot (website chatbot platform)

You may have noticed that the majority of them are chatbots. Chatbots, on the other hand, are one of the best ways to not only capture an email address, but also to obtain additional customer information and even directly sell products.
The following are the most effective ways to drive traffic to these tools:
Facebook ads (particularly effective when paired with ConvertBox)
Google Ads and YouTube Ads (a killer combination with ConvertBox or Conversiobot)

Influencer Marketing
Facebook organic marketing
Search Engine Optimization

If you can master even one of those traffic methods and use it to drive people to a high-converting optin or sales funnel, you’ll be well on your way to creating a recurring income.
Whether or not you choose to purchase this product through my link, I wish you the best of luck with your online business. If you do purchase the system, I hope to see you in the Facebook community! Please feel free to contact me via message or email at any time.

And if you do get the ebook through my link, please let me know so I can send you a copy of my book as a bonus!

Frequently Asked Questions (FAQs) About The Secret Email System
Here are some frequently asked product-related questions.
Is the secret email system bonus worth it?

In my opinion, the front end product and the majority of the bonuses are worth the price. I would have paid more just to gain access to Matt’s Facebook group!
What are the benefits of a hidden email system?
The main benefit is that you will learn one of the highest ROI business practices (email marketing) from someone who has built a seven-figure online business.

What do you call email marketing?
Email marketing is an important component of digital marketing for many businesses. Email marketing software is frequently referred to as an autoresponder, but a good email marketing platform will have more functionality.

Is this a legitimate way to make money online?
My secret email system review says it’s a great way to make money online as long as your online business uses marketing emails. It does require a list, but Matt teaches several methods for creating one.

Best Practices for Running Your Own Email Server

Plesk Premium Email, powered by Kolab lets you become your own mail service provider in a few easy steps. It’s like creating a personal Gmail service, one that you control from top to bottom. Running the mail server allows you to store your own email, access the mail server’s logs, and access the raw email files in a user’s mailbox.

However, one key concern when running your own mail server is email deliverability. Without being able to effectively reach your customer base, you cannot do business. So, how do you ensure your emails do not end up as spam?

It’s important to follow common rules and best practices when operating a mail server to guarantee your emails always reach their destination. In this quick guide, we’ll walk you through a few things to consider, to make sure that your emails always end up where you intend.

Reputation Management

Much of email delivery depends on your reputation, which is attached to your IPs and domains.

Please note that there might be different types of setups where you can either influence these things or not:

  • If you’re **running your own server **(or VPS – virtual private server) or a bunch of servers with Plesk for shared hosting with WHMCS, you have full influence and control about the following settings.
  • If you’re an **end customer or reseller **of a service provider or hoster using Plesk, unfortunately only your hosting provider can do these modifications for you. In case you want to regain control of your environments, it’s time to move your shared hosting account to your own VPS!
  • If you run Plesk on one of the hyperscale cloud providers such as DigitalOcean, Linode, AWS/Lightsail, Azure, or Google, your default email / SMTP (Port 25 or not) might be blocked on the infrastructure level. If that’s the case, you might need to contact their support to unblock it. In addition, also check that you’re receiving a reverse DNS entry for your IP that is required for operating an email server properly.

The two key-factors that we can influence are:

**1. Ensure other servers can distinguish **between genuine email coming from your server and spam coming from other servers, pretending to come from your server. If you don’t, a spammer can burn your hard-earned reputation while delivering their spam.

You can ensure this by enabling DKIM/DMARC and SPF protection in Plesk under “Server-Wide Mail Settings”.
