Sending domains: Optimize the deliverability of your mailings

The Sending domains feature helps you improve the deliverability of your mailings. You can create the optimal conditions for ensuring that your emails actually reach the recipient and are not classified as spam by specifying the right settings in the Sending domains feature . This way, you will strengthen your brand and your reputation as a sender.

How does the Sending domains feature specifically help improve deliverability?

• Use SPF (Sender Policy Framework) to ensure that only authorised senders can send emails from your domain.

• Use DKIM (DomainKeys Identified Mail) to sign your emails and ensure that the content of your emails cannot be tampered with.

• Use DMARC (Domain-based Message Authentication, Reporting and Conformance) to control what to do with dispatches from your domain for which authentication using SPF or DKIM fails.

• Use BIMI (Brand Message Identification) so that the recipient can recognise authenticated dispatches from your domain at first glance by your company logo.

Domain alignment is a prerequisite for SPF, DKIM and therefore also for DMARC and BIMI. The easiest way to implement domain alignment and optimise your deliverability is to delegate your subdomain to Inxmail via Domain delegation.

Use your domain for Inxmail only: Create a subdomain that you use exclusively for sending emails via Inxmail . If your main domain is example.com, you can create a subdomain such as newsletter.example.com.
