Make sure to get all the technical stuff (such as SPF, DKIM, and DMARC.) set up and right. 

Also, always optimize your emails for mobile device (for smartphone users) since most emails are read on those devices.

Or, you can look at your existing customers to see which device they use the most and optimize accordingly.

Average email click-through rates by industry

The click-through rate (CTR) is the percentage of people who clicked on a link in your email out of the total number of people who received it.

There are two types of email bounces: hard bounces and soft bounces. 

• Hard bounces are permanent failures, meaning that the email cannot be delivered because the email address is invalid or the recipient’s mailbox is permanently unavailable. 
• Soft bounces are temporary failures, which can occur for a variety of reasons, such as the recipient’s mailbox being full or the email server being down.

Average unsubscribe rate

The unsubscribe rate refers to the percentage of recipients who request to or opt out of your mailing list after receiving your emails.
