Netcore Email API (formerly Pepipost) is aimed at developers and enterprises, not typical WordPress operators. The entry paid plan starts at $25/month for 150,000 emails – a volume tier that few WordPress sites reach. A perpetual free tier (100 emails/day, approximately 3,000/month) exists for testing and low-volume use.
The platform handles both transactional and marketing email at scale. Its differentiator is infrastructure breadth (US, EU, and Indian data residency) and volume: the service processes large email volumes for enterprise customers. For a typical WordPress site sending hundreds or low thousands of emails per month, Netcore is overspecced and overpriced.

The free tier at 100 emails/day is adequate for a small WordPress site’s A transactional email is the automated message a WordPress site sends in response to a single user action – a password reset, an order confirmation, a form receipt – addressed to the user who triggered it.

The paid plans are enterprise-oriented: the $25/month entry point buys 150,000 emails – more volume than most WordPress sites need. If you actually send 150,000 emails/month from WordPress, Netcore’s per-email cost ($0.17/1K) is competitive with Amazon SES ($0.10/1K) and better than Mailgun at equivalent volume.
WordPress integration
FluentSMTP – FluentSMTP includes a native Pepipost/Netcore integration. Enter your API key, select Pepipost as the mailer, done.
Generic SMTP – Any mailer plugin (WP Mail SMTP, Post SMTP) can connect to smtp.pepipost.com using the SMTP settings above.
A dedicated Netcore WordPress plugin existed (Pepipost plugin) but appears to be no longer actively maintained. Use FluentSMTP or generic SMTP instead.
Assessment
Netcore Email API is a capable, enterprise-grade email infrastructure service with strong deliverability credentials. For the narrow use case of high-volume WordPress email (100K+ messages/month), it offers competitive per-email pricing on cloud-native infrastructure.
For WordPress sites at typical transactional volumes:
- Under 1,000/month: SMTP2GO free tier covers this with zero cost and zero complexity.
- 1,000-10,000/month: SMTP2GO Starter ($10/mo), Postmark ($15/mo), or Brevo (free for 300/day) serve this range with simpler setup and better WordPress ecosystem support.
- 10,000-100,000/month: Mailgun or Amazon SES are more commonly used in the WordPress ecosystem at this scale.
- 100,000+/month: Netcore becomes relevant alongside Amazon SES and Mailgun Scale plans.
The platform’s developer-focused interface and enterprise pricing make it a poor fit for most WordPress operators. The free tier (100/day) is functional but outmatched by competitors. Netcore earns consideration only when volume and infrastructure requirements push beyond what the WordPress-focused relay market typically serves.
