Postmark

Overview

Postmark is a transactional email service focused on one thing: speed and deliverability. It is designed for sending transactional emails (password resets, receipts, welcome sequences) instantly, ensuring they never end up in the spam folder.

Pricing & Free Tier

Free Tier: No. Offers a 30-day free trial for 100 emails.
Basic: $15/month for 10,000 emails.
Pro: $16.50/month for 10,000 emails, adding dedicated IPs.

How to Use

1. Sign up at postmarkapp.com and create a server.
2. Verify your sending domain.
3. Get your API token or SMTP credentials.
4. Integrate Postmark into your app (e.g., using their SDK).

Important Notes

• No Marketing Emails: Postmark strictly separates transactional (Postmark) from marketing/bulk emails (which they route to their sister product, ActiveCampaign). This is why their deliverability is so high.
• Price: It is slightly more expensive than SendGrid or Mailgun, but the speed and inbox placement are usually worth it.
