Reasons for testing the deliverability of your emails

Email deliverability generally stands for the ability to deliver emails to (subscriber’s) inboxes. People like email marketers use it to gauge the likelihood of email campaigns reaching their subscriber inboxes, related to actual delivery–like ISP, spam issues, throttling, bounces and bulk email.

Things that might hurt your email deliverability include: sending emails without custom authentication, sending with a free domain, using single opt-in, no possibility to unsubscribe, shortening URL’s in the email and a general lack of engagement by receivers receiving your mails.

As subscribers generally won’t notify you they are not receiving your mails, testings the deliverability of your mails is important. It will give you valuable insights into possible reasons for providers to block your emails or mark them as spam, handing you actionable opportunities for improvement that you could implement in order to optimize the deliverability of your mails.
