Email marketing

How is an email list cleaned before it costs your sender reputation?

Addresses are verified before they are sent to, bounces are watched after every send, and anyone who unsubscribes is never emailed again. A list is an asset only while it is clean.

Before a send

  • Verify the addresses.
  • Remove anyone who unsubscribed.
  • Remove duplicates.

After a send

  • Check the bounce rate.
  • Remove addresses that hard bounced.
  • Hold the next send if the rate is high.

The line we do not cross

Someone who has unsubscribed gets no more email from that list, whatever the reason for wanting to reach them.

Where this comes from

This is how our own team works every day. It is not taken from one client.
