Nonetheless, contemplating we handled all of the service suppliers equally in every take a look at (organising sender subdomains, authenticating information, and sending the identical electronic mail to the identical seed listing on the similar time), it’s clear that some suppliers are so much stronger in deliverability than others.

The highest three (ActiveCampaign, Fixed Contact and Drip) had lower than 6% of emails marked as spam.

Should you’re sending via MailChimp, this might have a big effect in your open charges as this tab is checked much less often.
