Setup steps

  1. 01

    SendGrid account + API key

    Sign up at sendgrid.com. Settings → API Keys → create Full Access key.

  2. 02

    Domain verification

    Add CNAME + TXT records to DNS. Verified domain reduces spam classification risk.

  3. 03

    SDK integration

    npm install @sendgrid/mail. `sgMail.setApiKey(key)` → `sgMail.send({to, from, subject, html})`. 5 lines of code.

  4. 04

    Dynamic templates

    SendGrid Dashboard → Dynamic Templates for HTML templates. Personalize with `templateId` + `dynamicTemplateData`.

  5. 05

    Webhook setup

    Event Webhook → bounce, spam report, unsubscribe, click, open tracking.

  6. 06

    Test + production

    Sandbox Mode for testing (no real sends) + production.

Common pitfalls

  • No domain verification = lands in spam
  • From address must be from a verified domain
  • No bounce management = deliverability drops
  • Unsubscribe list tracking (KVKK + CAN-SPAM)
  • Turkish character encoding (UTF-8 mandatory)

Frequently asked questions

SendGrid vs Mailgun vs AWS SES?

SendGrid: user-friendly dashboard, good deliverability, slightly expensive. Mailgun: technical, flexible, mid-price. AWS SES: cheapest ($0.10/1000), technical, configuration-heavy. SendGrid recommended for SMBs.

Commercial email under KVKK?

Explicit consent required for commercial comms (newsletter, campaigns). Transactional (order confirm, password reset) needs no consent — mandatory communication per contract. İYS registration required for email too.

How to improve deliverability?

Authenticate domain (DKIM + SPF + DMARC). Clean bounce lists. Engagement-based sending (active users first). Warm-up: send small volumes the first week, gradually increase.
