IP and Domain Warm-up Strategies

Today when sending an email campaign out the most important factor is your IP and domain reputation. In the old days, content filtering was the main method of filtering email into whether it was accepted and or if ends up in the bulk/junk/spam folder.

Now everything is based on user engagement. Meaning any action that the user does to an email message, whether it is opening the message, clicking links in the message, replying to the message, marking the email as spam, deleting the message, adding the contact to your address book, etc.

Tips for Warming up IPs and Domains.

Domain Configuration

We set up MX, SPF, DKIM, DMARC, and Sender ID records.

MX (Mail Exchange) records

The MX record tells the sending mail server where to deliver the mail.

SPF (Sender Policy Framework) records

Sender Policy Framework is a record that is used to help prevent email spoofing.

DomainKeys Identified Mail (DKIM) is a method for associating a domain name to an email, thereby allowing an organization to take responsibility for a message in a way that can be validated by a recipient.

Parking Your Own Domain for Mailing

Warning: If you park your domain any active domain, email service, or any other service tied to that domain will not work anymore.

Create two nameservers at your domain registrar.

ns1.yourdomainname.com and ns2.yourdomainname.com
Then point those two nameservers to one of your sending IPs.

Last point the domain to the new nameservers ns1.yourdomainname.com and ns2.yourdomainname.com

How to check Domain and IP Reputation?

Email service providers treat domains differently based on their reputation. This “score” can be based on many things, such as the age of the domain name, how well the sending account has been set up, deliverability, engagement data from users receiving email from it, and – often to a higher degree – previous listings of domain names and IP addresses on anti-spam services such as SpamHaus.

You can use MXToolbox to check your domain and IP reputation against many popular blocklists.
