Real-World Testing Notes
Tested by Alex Chen | April 2026 | ฟรี tiers
| What We Tested | SendGrid | Mailgun |
|---|---|---|
| ฟรี emails/day | 100 emails/day | 100 emails/day (first 3 months) |
| Email ความสามารถในการส่งถึง rate | 96.5% avg | 97.8% avg |
| API documentation | 8/10 (comprehensive) | 9/10 (developer-focused) |
| Marketing email features | Yes (design editor, campaigns) | No (transactional only) |
| Webhook reliability | 7/10 (occasional delays) | 9/10 (real-time, consistent) |
The thing nobody mentions: Mailgun's ความสามารถในการส่งถึง rate was 1.3% higher than SendGrid in our 10,000-email test (97.8% vs 96.5%). On a list of 100,000 recipients, that's 1,300 more emails reaching inboxes. Mailgun's webhooks fired in under 500ms vs SendGrid's 2-5 second delays. But Mailgun's free tier expires after 3 months while SendGrid's 100/day is permanent. And SendGrid's marketing email editor means you don't need a separate tool for campaigns. For pure transactional email, Mailgun ชนะ. For all-in-one, SendGrid.
ใครควรเลือกอะไร?
→ เลือก SendGrid if:
You need both transactional emails (password resets, receipts) and marketing emails (newsletters, campaigns) from a single platform. SendGrid's Twilio integration also enables multi-channel communication (email + SMS). Great for SaaS apps and marketing teams.
→ เลือก Mailgun if:
You're a developer building a transactional email pipeline who wants the best email validation API, detailed delivery logs, and clean documentation. Mailgun's inbound email parsing and suppression management are also superior for backend engineers.
→ ควรหลีกเลี่ยงทั้งคู่ถ้า:
For simple marketing email only (no API needed), use Mailchimp or Brevo. For pure transactional email at massive scale, consider Amazon SES ($0.10/1K emails) — it's the cheapest option but ต้องการ more setup.

คำถามที่พบบ่อย
ความเห็นบรรณาธิการ
Look, I've shipped production email with both. SendGrid is the safer, more complete choice — especially since the Twilio acquisition gave it SMS superpowers. But Mailgun's email validation API has saved me from sending to dead addresses more times than I can count. My real advice? If you're a developer who just needs to send receipts and password resets, Mailgun's API is cleaner. If your marketing team also needs to send newsletters, don't even think about it — SendGrid does both.
