Step-by-step

Sign up + add your domain

sendlayer.com → sign up. In the dashboard go to Settings → Domains → Add Domain. Add the DNS records SendLayer provides (SPF, DKIM).

Generate SMTP credentials

SendLayer → Settings → API Keys (or SMTP credentials). Generate a new key and copy the username + password.

Add the connection in SendGrail

SendGrail → Connections → Add Connection → pick SendLayer.

Fill in: Connection Name, From Email (your verified domain address), From Name, Username + Password. Save.

Test

SendGrail → Test Email → pick SendLayer → send.

Troubleshooting

• Authentication failed — wrong credentials. Regenerate at SendLayer → Settings.
• From Email rejected — domain not verified. Add DNS records and re-verify in SendLayer dashboard.
• Plan limit reached — check your subscription's quota in SendLayer.

What's next

• Email Routing — route through SendLayer for transactional, others for marketing.
• Failure Alerts — get pinged on rejections.
