This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.

Install straight from GitHub with WP-CLI:

wp plugin install https://github.com/getpoststack/wordpress-plugin/archive/refs/heads/main.zip

No built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.

Readme github.com/getpoststack/wordpress-plugin ↗

Replace the default WordPress mailer with the PostStack Email API for reliable transactional delivery, open/click tracking, and detailed deliverability analytics.

Description

PostStack for WordPress hooks into wp_mail() and forwards every outgoing message through the PostStack Email API — an EU-hosted, GDPR-compliant email service up to 75% cheaper than Resend, SendGrid, and Postmark. PHPMailer is bypassed entirely, so misconfigured SMTP settings can never silently swallow mail.

Features:

Drop-in replacement — works with WooCommerce, contact forms, password resets, and any plugin that calls wp_mail().
Configure once via Settings → PostStack — paste your API key and default From address.
Per-message From overrides via the standard From: header.
Real-time open/click tracking and deliverability analytics in the PostStack dashboard.
EU data residency — your email data never leaves the European Union.

Get started and grab an API key at https://poststack.dev. Full documentation lives at https://poststack.dev/docs. Free tier includes 3,000 emails/month with no credit card required.
