How good is your email deliverability?

Starting in February 2024, Gmail and Yahoo are rolling out new authentication requirements which require using a custom DKIM authenticated domain with DMARC reinforced.

In April 2025, Microsoft joined them with a similar announcement.

GetResponse strongly advises all senders to use email addresses from their own private domains

as a from email address, and to configure both DKIM and DMARC.

At GetResponse we are frequently asked about the quality of our deliverability

rate. Because deliverability depends on many factors, including the content of your messages, the deliverability rate could vary for each mailing. For all our customers collectively, however, we are proud to say our overall deliverability rate currently stands at 99%.

This rate is achievable only when best email marketing practices, as defined by organizations like M3AAWG, CSA, Spam

Signal, or other similar, are used by the Customer. You can find more information here: Documents for Senders and ESPs | M3AAWG .

GetResponse supports our Customers and their deliverability also by: maintaining memberships with M3AAWG, CSA, SpamSignal; leveraging industry-leading technology: SpamAssasian and SpamHaus public blacklist data; and adhering to all regulatory requirements like GDPR and CAN-SPAM.

Please note that there are various deliverability statistics available provided by different professional email software testers and the results may vary depending on the method of the tests.

In the email marketing world, deliverability is strictly connected with reputation. The better reputation, the better deliverability is.

Email delivery and GetResponse policies

Over two decades GetResponse has developed a very good relationship with all major Internet Service Providers (ISPs). This all would not be possible without our strict import

policy, ZERO tolerance to SPAM, list management tools, delivery tracking and processing the undeliverable email addresses and enforcing best practices.

As a shared email marketing software, we allow users to use our servers and IP addresses

to manage the delivery of the messages of all your customers. The advantage of a shared IP address space is that from day 1 you can send a large volume of messages to your contacts because of the already established reputation of IP addresses.

Sender reputation

Sender reputation is the relationship we build with ISPs

in order to increase and maintain the deliverability. The higher our reputation is the higher the chance that your message will be delivered straight to the recipients. There are many factors which influence deliverability: quality of the traffic that is being sent from the IP, domain, and also the quality of the mailings sent by a particular sender (the from field reputation).

IP address and domain reputation

The IP address and domain reputation is under constant control of the appropriate GetResponse team which enforces best practices, controls the statistics and suspends accounts

of users that abuse our system.

GetResponse IP addresses

To check the reputation of our IP addresses you can use SenderScore.org, which provides information on how a sender’s reputation compares to other email senders, and how it is likely to be evaluated by mailbox providers. The current range of our IP addresses is following:

104.160.64.0/24
104.160.65.0/24
104.160.67.128/25
104.160.68.224/27
104.160.69.0/26

The SPF

record is the following:

v=spf1 mx a include:_spf.getresponse.com -all
