Why Consider Alternatives to Netcore/Pepipost

The acquisition created some uncertainty

Pepipost being rebranded to Netcore Email API in 2020 means the platform you signed up for has changed ownership. Some users prefer platforms with more stable ownership.

You need marketing features

Netcore Email API focuses on transactional delivery. If you've grown to need marketing automation, sequences, or subscriber management, you'll need to either add another tool or switch to an all-in-one platform.

The pricing model is complex

While "opened emails free" sounds great, understanding your actual costs requires predicting open rates. Some teams prefer simpler per-email or per-subscriber pricing they can easily budget.

You want modern developer experience

Netcore's API works, but tools like Resend and Postmark offer more modern developer experiences with better SDKs, documentation, and integrations like React Email.

What Happened to Pepipost?

First, the context: Pepipost was acquired by Netcore in 2020 and rebranded to Netcore Email API. If you're searching for "Pepipost alternatives," you're really looking for alternatives to Netcore Email API.

Netcore is a broader customer engagement platform, and the Email API is their transactional email product. They've kept the technology but integrated it into their larger ecosystem.

Why People Look for Alternatives

The Acquisition Changed Things

When a smaller company gets acquired, things change. Pricing, support, product direction—all can shift. Some users prefer platforms with more predictable futures. Learn more in our Pepipost comparison page.

Marketing Features Are Separate

Netcore Email API focuses on transactional delivery. If you need marketing automation, email sequences, or subscriber management, you'll need to add another tool or switch to an all-in-one platform like Sequenzy or Brevo.

The Pricing Model Is Unique

Netcore's "opened emails free" model sounds great, but it makes budgeting complex. You need to predict open rates to estimate costs. Some teams prefer straightforward per-email or per-subscriber pricing.

The Alternatives, Honestly

If you want marketing + transactional: Sequenzy

Netcore is transactional-only. If you've grown to need welcome sequences, drip campaigns, and subscriber segmentation, you need a full platform.

Sequenzy combines both with AI content generation and Stripe integration. Our AI writes content; Netcore's AI optimizes delivery—different purposes.

If you want modern developer experience: Resend

Netcore's API works, but Resend has the best developer experience in email. React Email templates, modern SDKs, beautiful documentation. Transactional only, though—no marketing features.

If deliverability is critical: Postmark

Postmark's exceptional deliverability comes from strict customer vetting. They reject questionable use cases to protect IP reputation. If password resets and 2FA codes must arrive, Postmark is purpose-built for this.

If cost is everything: Amazon SES

At $0.10 per 1,000 emails, nothing beats SES on raw cost. But you get zero help—no templates, no dashboard, no deliverability tools. Only choose this if you have engineering resources to build everything yourself.

If you want budget + features: Elastic Email

Elastic Email at $0.09/1k is even cheaper than Netcore. Both transactional and marketing included. The DX is dated and deliverability can be inconsistent, but for budget-conscious teams, it works.

The Pricing Comparison

At 50,000 emails/month:

  • Netcore: ~$25/month (with "opened emails free" credits)

  • Amazon SES: $5/month (DIY everything)

  • Elastic Email: ~$9/month (budget with features)

  • Resend: $20/month (transactional only, best DX)

  • SendGrid: $19.95/month (transactional + marketing)

  • Sequenzy: $19/month for 10k emails (marketing + transactional + AI)

Note: Some prices are per subscriber (Sequenzy) while others are per email (Netcore, Resend). Compare based on your actual usage. See our pricing page for details.

When Netcore/Pepipost is Still the Right Choice

Netcore wins if:

  • You need enterprise-scale transactional (50B+ platform volume)

  • The "opened emails free" model significantly reduces your costs

  • AI send-time optimization improves your delivery metrics

  • You have strong Asia-Pacific audience (regional infrastructure)

  • You only need transactional, no marketing features

Don't switch just because alternatives exist. If Netcore's unique features are saving you money or improving deliverability, the switching cost might not be worth it. But if you need marketing features or prefer more modern DX, the alternatives are solid.

Frequently Asked Questions

Pepipost was acquired by Netcore in 2020 and rebranded to Netcore Email API. The technology and team integrated into Netcore's broader platform. If you're looking for "Pepipost," you're now looking for Netcore Email API.

Resend for best developer experience with transactional only. Postmark for exceptional deliverability. Sequenzy if you also need marketing features with AI content generation. All three have cleaner APIs than most alternatives.

Yes, especially for enterprise transactional at scale. Their AI send-time optimization and "opened emails free" model are genuinely unique. But if you need marketing features or prefer more modern DX, alternatives may suit you better.

Amazon SES at $0.10/1k emails is cheapest if you can DIY everything. Elastic Email at $0.09/1k is next cheapest with some features included. ZeptoMail's pay-as-you-go ($2.50/10k) is affordable with no monthly commitment.

Similar capabilities. Netcore has unique AI optimization and pricing model. SendGrid has larger Western market presence and Twilio ecosystem. Netcore is stronger in Asia-Pacific. SendGrid has more marketing features.

No, we don't have AI send-time optimization. Our AI focuses on content generation—describing what you want and having AI write the emails. Different AI focus, different value proposition.

Sequenzy if you need marketing automation, onboarding sequences, and Stripe integration alongside transactional. Loops if you want SaaS-focused email without AI. Customer.io if you have budget for powerful behavioral automation.

For transactional, swap API integration to your new provider. Netcore doesn't have subscriber lists to export (API-only). If you're adding marketing features, you'll import contacts from your application database, not from Netcore.

Unique pricing where opened emails return as credits—they don't count against your quota. Rewards good engagement. None of the alternatives have this exact model. Closest is pay-as-you-go pricing from ZeptoMail.

For self-hosted email sending, Listmonk is excellent for newsletters, Postal for mail server infrastructure, and Mautic for full marketing automation. All require self-hosting and SMTP relay setup.

Contact Netcore support to cancel your subscription. For enterprise contracts, check your agreement terms. Export any API keys and integration documentation before canceling. There's no self-serve cancellation for most plans.

Netcore Email API starts at $25/mo for 150k emails with unique "opened emails free" credits. Pricing scales with volume. Enterprise plans are custom quoted. The "opened emails free" model rewards high engagement senders.

Netcore Email API is transactional-focused with no subscriber lists to export. You can access delivery logs via API. Templates may need to be copied manually. Your subscriber data lives in your own application, not in Netcore.

Netcore offers a free trial to test the API. No permanent free tier like some competitors. Contact sales for trial access. Test your integration before committing to paid plans.

Netcore's refund policy varies by plan type. Contact support for billing issues. Enterprise contracts have specific terms. Generally, prepaid credits are non-refundable. Check your agreement for specific terms.
