DNS Setup for 1&1 IONOS

The following guide is relevant for SMTP2GO customers, who have a domain name hosted with 1&1 IONOS.

Step 1

Log in to your 1&1 IONOS account and go to the Domains and SSL section.

Step 2

Next to your domain, click the gear symbol under Actions and select DNS.

Step 3

Click Add Record and select type CNAME.

Step 4

Enter the Hostname we recommend into the Hostname field.
Note: You may only need to add the first part of the recommended hostname and not your full domain name to your DNS records as your provider may automatically add it.

Enter the Value that we advise for your CNAME record into the Value/Points to field.

Optional: Select the desired TTL.

Click the Save button.

Repeat steps 3 and 4 for each required CNAME record.

You can find the "Hostname" and "Value" on the Sending > Verified Senders > Sender domains section of your SMTP2GO Dashboard.
