Custom "From" Email — DNS Setup Guide

If you're on the Unlimited plan and use a custom "From" email address for lead notifications, you'll need to verify your domain by adding a few DNS records. This ensures your emails are properly authenticated and land in your recipients' inboxes.

We'll provide you with 3 CNAME records to add to your domain's DNS. These are DKIM (DomainKeys Identified Mail) records that prove you've authorized LeadSync to send emails on behalf of your domain.

What you'll need

  • Access to your domain's DNS settings (usually via your domain registrar or hosting provider)
  • The 3 CNAME records provided by LeadSync support

What the records look like

Each record has two parts:

  • Name (also called "Host"): A long string ending in ._domainkey
  • Value (also called "Points to" or "Target"): A long string ending in .dkim.amazonses.com

For example:

Type Name Value
CNAME abc123._domainkey abc123.dkim.amazonses.com

You'll have 3 records like this — all need to be added.

Tip

Some providers automatically append your domain to the record name. If the name field already shows .yourdomain.com, only paste the part before your domain. For example, if the full name is abc123._domainkey.yourdomain.com, just enter abc123._domainkey.

After adding the records

DNS changes can take up to 48 hours to propagate, though most providers update within 5-30 minutes. Once the records are detected, your custom "From" email domain will be fully verified and your lead notifications will be authenticated.

You don't need to do anything else — we'll confirm on our end when everything is verified.
