To live out our “working in public” value, we publish monthly deliverability reports to give you insight into ConvertKit’s performance. (June 2020)
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:
If you missed previous Deliverability reports, you can check them out below:
In June, ConvertKit sent over 1 billion messages (1,002,348,965 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 June, our system-wide delivery rate was 99%.
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.
Here are the top 5 domains ConvertKit sends to in terms of volume:
Volume: 581 million messages
Delivery rate: 99.48%
Volume: 99 million messages
Delivery rate: 99.92%
Volume: 91 million messages
Delivery rate: 99.88%
Volume: 23 million messages
Delivery rate: 99.95%
Volume: 11 million messages
Delivery rate: 99.90%
The average open rate of all emails sent through ConvertKit was 30.3%.
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 June was 0.009%, which speaks to the high quality of mail sent by our customers and the healthy reputation of our infrastructure.
Deliverability tip of the month:
Keep your email size below 100KB
If your emails are too large, there’s a chance they might be clipped by your subscribers’ mailbox providers. When a message gets clipped, the pixel that tracks opens gets clipped as well. This means, subscribers are opening your email, but their opens aren’t being counted. This could be the cause of a drop in open rates.
