<p>One of our <a href="https://convertkit.com/mission" target="_blank" rel="noopener">values</a> 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 <a href="https://convertkit.baremetrics.com/" target="_blank" rel="noopener">finances</a>.</p>
<p>One commonly asked question by creators looking for a new email marketing platform is, <em>“How is your email deliverability?”</em></p>
<p>Here is our monthly deliverability report to answer that question:</p>
<p>If you missed previous Deliverability reports, you can check them out below:</p>

</ul>
<h2>In April, ConvertKit sent over 1.2 billion messages (1,250,608,097 to be exact).</h2>
<p>When messages are sent, they can be <strong>delivered</strong> or they can <strong>bounce</strong>. For more details on how email deliverability operates, check out our blog post <a href="https://convertkit.com/sender-reputation" target="_blank" rel="noopener">here</a>. But for a little TLDR- The more messages delivered, the better!</p>
<p>It is inevitable for <em>some</em> 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.</p>
<h2>In April, our system-wide delivery rate was <span style="color: #99cc00;">99.7%.</span></h2>

<p>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.</p>

<p><strong>1. Gmail.com</strong><br />
Volume: 744 million messages<br />

<h2>The average open rate of all emails sent through ConvertKit was <span style="color: #99cc00;">29.3%.</span></h2>
<p>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:</p>

<p>I talk more about open rates and why they aren’t always reliable in <a href="https://convertkit.com/sender-reputation" target="_blank" rel="noopener">this article</a>.</p>
<h2>The average click rate across ConvertKit accounts was 5.53%.</h2>
<p>We calculate click rate by dividing the number of subscribers who clicked a link by the total number of subscribers who received the email.</p>
<p>Similarly, the average click-to-open rate was <strong>16.22%</strong>. This is calculated by dividing the number of subscribers who clicked a link by the number of subscribers who opened the email.</p>
<p>Our system-wide complaint rate remained over 10x lower than industry standard</p>
<p>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.</p>
<p>In the email industry, a complaint rate less than 0.1% is seen as healthy. <strong>ConvertKit’s complaint rate in April was 0.007%</strong>, which speaks to the high quality of mail sent by our customers and the healthy reputation of our infrastructure.</p>

<h2>Deliverability tip of the month:</h2>
<p>Encourage your subscribers to reply to your messages! This sends a positive signal to mailbox providers and can help boost your <a href="https://convertkit.com/sender-reputation" target="_blank" rel="noopener">sender reputation</a> and improve deliverability.</p></blockquote>
