One of our values at ConvertKit is to work in public. We strive for transparency, which is why we share information that is typically kept private, such as our finances.

One commonly asked question by creators looking for a new email marketing platform is, “How is your email deliverability?”

Here is our monthly deliverability report to answer that question:

In April, ConvertKit sent over 1 billion messages (1,076,866,639 to be exact).

When messages are sent, they can be delivered or they can bounce. For more details on how email deliverability operates, check out our blog post here. But for a little TLDR- The more messages delivered, the better!

It is inevitable for some messages to bounce due to invalid addresses, full mailboxes, etc., but a good delivery rate indicates healthy deliverability for ConvertKit. We consider a system-wide delivery rate of 98% and above to be very healthy.

In April, our system-wide delivery rate was 98.9%

This high delivery rate indicates a healthy reputation for ConvertKit, which gives our customers a solid foundation for their email deliverability. To get even more detailed about how well we’re performing, it helps to filter down by mailbox provider.

Volume: 602 million messages
Delivery rate: 99.55%

The average open rate of all emails sent through ConvertKit was 32.3%.

Senders often ask how their open rates stack up to others. Truth is, open rates can vary greatly depending on your industry and audience type (B2B vs. freemail addresses, for example). However, here’s a general scale you can use to measure your performance:

I talk more about open rates and why they aren’t always reliable in this article.

Our system-wide complaint rate remained over 10x lower than industry standard

A complaint is when a subscriber marks a message as spam. An elevated complaint rate is a signal that the sender’s quality of mail isn’t good. We have a team dedicated to ensuring that the mail sent from ConvertKit is wanted by the recipients.

In the email industry, a complaint rate less than 0.1% is seen as healthy. ConvertKit’s complaint rate in April was 0.009%, which speaks to the high quality of mail sent by our customers and the healthy reputation of our infrastructure.

Tabs might be coming to Outlook and Hotmail

You’re probably very familiar with Gmail’s Promotions, Social, and Updates tabs. It appears that Microsoft might be working on rolling out a similar feature within Hotmail and Outlook.

Some Hotmail and Outlook users have reported that they have the option to turn on Promotions, Social, and Newsletters tabs. Microsoft will still have a Focused tab that operates like the Primary tab in Gmail.

For senders, this means it’s even more important to stand out in the Promotions tab by sending engaging, relevant emails. If your emails land in the Promotions tab but they are not promotional emails, you can ask your subscribers to drag your message to the Primary or Focused tabs to help Gmail and Microsoft’s algorithms learn where to place your messages.
