Top delivery rates

At dotMailer, getting your email campaigns past spam filters and into inboxes is something we take pride in.

As a dotMailer client, you’ll benefit from an armoury of crucial advantages we have in this area, including:

Over 11 years email broadcasting reputation
Incredibly powerful 'Data Watchdog' system that monitors and polices ALL user data before it gets uploaded. The Watchdog predicts, detects and prevents email abuse - protecting our sender reputation and your delivery rates. Over 4,000,000,000 data checks to date, and counting!
Strictly enforced anti-spam policy maintains our reputation amongst recipient ISPs
Our early adoption of the Sender Policy Framework means we’ve been sending authenticated emails for many years – we know authentication inside out, so your emails get the green light from ISPs
We are subscribers to the major ISP Feedback Loops – so your data gets automatically cleaned by dotMailer, before a complaining recipient can get you black listed
We are members of the DMA and the IAB (our Business Development Director sits on the board of the DMA’s Email Marketing Council) – so we are experts in best practice for email deliverability.
We are UK-based (the vast majority of spam emails originate from overseas providers)
We are both Return Path Sender Certified and Goodmail accredited. That means we can enable you to take advantage of guaranteed delivery into inboxes, with links and images turned on, and with video embedded in many cases
We promote and enforce compliance with the policies of the Spamhaus Block List (find out more)
We’ll go out of our way to give you expert advice and guidance on how to write and tailor your emails to make sure they are less likely to trigger spam filters.
