When setting up your sending domain, you will need to add the DNS records to authenticate your domain and get the best deliverability possible for your emails.
Send Your DNS Information to Your Administrator
To get your domain authenticated go to the ⚙️-> Domains & IPs and either send them to your DNS administrator or if you have access you can copy the fields from the table. To email them to your DNS administrator select the email the full list of DNS records as shown below and enter the email address of your administrator.
Once your administrator has updated the DNS records you can come back into this screen and click Verify all DNS Records at the top of the table. The authentication usually takes 10-15 seconds. Once verified, the status for all the records should become green checkboxes.
If the entries do not verify, the DNS entries may still be propagating, which can take up to 30 minutes after your administrator makes these changes; wait a few minutes and try again. If you have issues with this step, please reach out to firstname.lastname@example.org with questions.
