ฟีเจอร์ ภาพรวม
Postmark's secret weapon is focus. By refusing to send marketing/bulk email, they keep their IP reputation pristine. Your password reset emails land in the inbox, not spam. The API is beautifully documented, delivery is typically under 10 seconds, and their 45-day activity log makes debugging email issues straightforward. Developers who use Postmark rarely leave.

ฟีเจอร์ ภาพรวม
SendGrid (owned by Twilio) is the most popular email API, used by companies like Uber, Airbnb, and Spotify. It จัดการ both transactional and marketing email in one platform. The free tier of 100 emails/day is genuinely useful for development. However, the biggest complaint is account suspensions — many developers report losing email capability overnight with minimal explanation.

คำถามที่พบบ่อย
ความเห็นบรรณาธิการ
We switched from SendGrid to Postmark after our third unexplained account suspension. Our password reset emails were hitting spam for 8 hours while we begged support to re-enable the account. Postmark มีค่าใช้จ่าย a bit more per email, but my CEO has never woken up to "why can't our ผู้ใช้ log in" since. If your emails are mission-critical, pay for Postmark. If you just need a development sandbox, SendGrid's free tier is fine.
