Custom Tracking Domain for Click URLs

Why Use a Custom Tracking Domain#

By default, AcelleMail wraps every link in your emails with its own tracking domain. If subscribers see clicks.acelle.io in URLs, it looks suspicious and can trigger spam filters. A custom tracking domain like track.yourbrand.com improves trust and deliverability.

Step 1: Create the CNAME Record#

Add this DNS record at your domain registrar or DNS provider:

Host:   track.yourbrand.com
Type:   CNAME
Value:  yourserver.com   (or the IP via an A record)
TTL:    3600

Wait for propagation (typically 15 minutes to a few hours).

Step 2: Configure Nginx for the Subdomain#

Create /etc/nginx/sites-available/track.yourbrand.com:

server {
    listen 80;
    server_name track.yourbrand.com;
    location / {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header Host \$host;
        proxy_set_header X-Real-IP \$remote_addr;
    }
}

Enable and reload: sudo ln -s ../sites-available/track.yourbrand.com /etc/nginx/sites-enabled/ && sudo nginx -s reload

Step 3: SSL Certificate#

sudo certbot --nginx -d track.yourbrand.com

Certbot will auto-configure the HTTPS block.

Step 4: Set in AcelleMail#

Go to Settings → Sending Domains → [your domain] → Tracking Domain. Enter https://track.yourbrand.com and save.

Test by sending a test email and hovering over a link — it should now show your custom domain.
