Adding DKIM Security to Your Custom Email Domain

Send secure emails from your own domain instead of This requires new DNS records.

Updated over a week ago


Envoy offers the ability for companies to send emails via their own domains that are secured using DomainKey Identified Mail (DKIM). DKIM verifies that emails are safe and really from the sender domain. It uses a digital signature to lock and verify emails, like putting a unique stamp on a letter. This helps to keep email conversations secure and trustworthy.

How it works

When it comes to email, we want to ensure that emails are not tampered with and that they come from who they claim to have. DKIM ensures emails are authentic by adding a header containing a unique and encrypted digital signature. When you receive an email, your email service looks at this signature included in the email's data. Your service then compares the private signature given in the email to the public key located in the DNS. From here, your email service can accept the email as valid or flag it as spam.

Once this is enabled on your Envoy instance, Envoy will be able to send valid emails that are addressed from your domain. They will not be flagged as spam or suspicious due to the validation happening with DKIM.

What it looks like

When your email invitations are sent to visitors, they come from [email protected].

With this feature enabled, you can use your own email domain instead.

Using your own email domain allows you to maintain your brand image. Visitors will receive an email that appears to come from your company directly, allowing for consistency.

How to enable

Envoy can enable this service for your account by request. Due to the sensitivity of this configuration, you will only be able to enable this with assistance from Envoy. Please get in touch with our support team at [email protected] or your account manager to enable this feature.

Your system admin will need to have DNS authority in order to implement this. Envoy is not responsible for any DNS outages or bounced emails that may occur if configured incorrectly on your domain.
