Setting up your MailerSend DKIM record is crucial to ensuring your emails reach inboxes without being flagged or blocked. DKIM cryptographically signs emails sent from MailerSend, allowing receiving mail servers to verify their authenticity and reducing the risk of spoofing while improving deliverability.
This quick step-by-step guide walks you through configuring DKIM in MailerSend and verifying that your DNS is correctly set up.
How to Set Up DKIM for MailerSend
Log in to your MailerSend account
Go to Email > Domains
In the Domains page, click on Add Domain
Add your domain name (company.com) and click Add domain.
You can choose automatic setup and authorize your hosting provider by giving a one-time permission to connect your domain.
Or choose “manual setup” to continue manual configuration.
MailerSend will display your DKIM record. Copy this record and paste it into your DNS management console.
Once your DNS changes have finished propagating, head back to your MailerSend dashboard, check the box labeled “I have added DNS records,” and click “Finish verification.”
