What is DKIM and why does it matter?#

DKIM (DomainKeys Identified Mail) is a DNS record that proves your emails genuinely come from your domain. Without it, email providers like Gmail, Outlook, and Yahoo treat your campaigns with suspicion — and a significant portion will land in spam or be blocked entirely. We do not allow emails to be sent using Gmail, Outlook, or Yahoo email addresses.

Setting up DKIM takes about 10 minutes and requires access to your domain's DNS settings (via your registrar — GoDaddy, Cloudflare, Namecheap, etc.).

Step 1 — Open Email Deliverability settings#

Navigate to Settings → Marketing Channel → Email → Sender Authentication. This page shows all domains you have configured for sender authentication.

Step 2 — Add your sending domain#

Click Add Domain and enter the domain part of your sender email address. For example, if your sender is marketing@acme.com, enter acme.com.

AI Engage CRM generates a set of DNS records — specifically a DKIM TXT record — that you need to add to your domain's DNS settings.

Step 3 — Add the DNS record to your domain#

Copy the DKIM record shown on the Deliverability page. Then:

1. Log in to your domain registrar (GoDaddy, Cloudflare, Namecheap, Google Domains, etc.)

2. Open the DNS settings for your domain

3. Add a new TXT record with the name and value shown in the CRM

4. Save the DNS record

Check the following example of 3 CNAME records to set up your dedicated sending domain:

Step 4 — Verify the setup#

Return to Settings → Email → Sender Authentication and click Validate next to your domain. The CRM checks for the DNS record and updates the status to Verified when found.

If verification fails, double-check that:

• The TXT record name and value are copied exactly (no extra spaces)

• The record has had enough time to propagate

• You are not using a Cloudflare proxy on the record
  

  

Once your domain is verified, you can start sending emails to your customers.
