Email (SMTP)
Sending order confirmations and marketing email.
Email carries order confirmations, receipts and marketing. Without it a customer pays and hears nothing, which generates support messages immediately.
Choose a provider first
Do not use a personal Gmail account. It has low sending limits, will start marking your own mail as spam, and can lock the account for bulk sending. Use a service built for transactional email.
Any SMTP provider works. Common choices: Amazon SES, Brevo, Mailgun, Postmark, Zoho Mail.
Connecting it
Integrations → Email (SMTP):
| Field | What to enter |
|---|---|
| SMTP host | From your provider, e.g. smtp.gmail.com. |
| Port | 587 for TLS, 465 for SSL. 587 is the usual answer. |
| Username | Usually your full email address, or an API key name. |
| Password | The SMTP password or API key. Not your account login, on most providers. |
| Encryption | Match the port: TLS with 587, SSL with 465. |
| From address | e.g. no-reply@yourbrand.com. Must be on a domain you control. |
| From name | Your brand name. This is what customers see in their inbox. |
Making mail actually arrive
Sending is easy; landing in the inbox is not. Three DNS records at your domain registrar decide it, and your provider will give you the exact values:
| Record | What it does |
|---|---|
| SPF | Says which servers may send as your domain. |
| DKIM | Signs your mail so it cannot be forged. |
| DMARC | Tells inboxes what to do with mail that fails the other two. |
Without SPF and DKIM your order confirmations go to spam. Not sometimes — routinely, at Gmail and Outlook especially. This is the step people skip and then conclude "email does not work".
Testing it
- Press Test — that confirms the SMTP credentials connect.
- Place a real test order and check the confirmation arrives.
- Check it at Gmail and Outlook specifically, not only your own domain.
- Look in the spam folder. Arriving in spam is a failure, not a pass.
Common problems
| Symptom | Cause |
|---|---|
| Connection refused or timeout | Wrong port, or the host blocks outbound SMTP |
| Authentication failed | Using your account password where the provider wants an SMTP key |
| Sends, but lands in spam | SPF or DKIM missing |
| Works, then stops | Daily sending limit reached |
| Rejected "from address not allowed" | The from address is on a domain the provider has not verified |
