Yes. Mailchimp Transactional lets you track open rates for your transactional emails through the Transactional API. Mailchimp Transactional tracks opens by adding a 1-pixel square graphic at the bottom of HTML emails. When a recipient downloads images in your message (which happens by default with most email clients) this is recorded as an open.
Monitoring opens helps you understand whether recipients are actually seeing your messages. And, with Mailchimp's 99% delivery rate, your emails are more likely to land in the inbox instead of the spam folder, which directly impacts how many people open them.
Yes. Mailchimp Transactional lets you track click activity within your transactional emails through the API. If you're noticing low click rates, here are a few things worth testing:
Note: Click tracking is not available in demo accounts. You'll need a paid account to use this feature.
Yes. Mailchimp Transactional lets you monitor your bounce rate for your transactional emails. Keeping bounces low protects your sender reputation and helps ensure future emails continue reaching the inbox.
Mailchimp Transactional has maintained a median bounce rate of just 2.69% across more than 300 billion emails sent since 2018, so the infrastructure is built to support strong deliverability at scale. For more details, explore our Transactional API documentation.
