What Happened to Pepipost?

First, some context: Pepipost was acquired by Netcore in 2020 and is now called Netcore Email API. The technology and team integrated into Netcore's broader customer engagement platform. If you're researching "Pepipost," you're really researching Netcore Email API.

These Are Different Tools

Netcore Email API and Sequenzy solve different problems.

  • Netcore is enterprise email infrastructure with AI-powered delivery optimization. They focus on massive scale (50B+ emails/month across their platform), deliverability intelligence, and unique pricing where opened emails don't count against your quota.

  • Sequenzy is a full email platform for SaaS. It combines transactional emails, marketing campaigns, and automation in one place.

Comparing them directly is a bit like comparing email infrastructure to a marketing platform. Both involve email, but they're optimized for different needs.

When should you choose Sequenzy?

1. You Need Marketing Automation

Netcore Email API is email infrastructure—API/SMTP for sending, no marketing features. If you need welcome sequences, drip campaigns, triggered automations, or audience segmentation, Netcore doesn't do this. Sequenzy has a full automation builder.

2. You Want AI-Generated Content

Describe what you want ("a 5-email onboarding sequence for a project management SaaS") and our AI generates the entire sequence. Netcore's AI (Raman) is for delivery optimization—send times, throughput—not content creation. Different AI, different purpose.

3. You Need Subscriber Management

Netcore doesn't have subscriber lists, segments, or contact profiles. You manage all that in your own application and call their API when you want to send. Sequenzy gives you a full subscriber management system with tags, segments, and custom fields.

4. You Need Stripe Integration

Sequenzy connects directly to Stripe via our native integration—syncing customer data, subscription status, MRR, and churn signals. Netcore doesn't integrate with billing systems.

5. You Want One Platform

If you're tired of juggling Netcore for transactional + another tool for marketing + maybe another for automation, Sequenzy combines everything in one dashboard.

When should you stick with Netcore/Pepipost?

1. You Need Enterprise Scale

Netcore handles 50B+ emails per month across their platform. They're built for enterprise senders with complex delivery requirements. We're focused on SMB SaaS companies, typically under 100k subscribers.

2. The "Opened Emails Free" Model Matters

Netcore's unique pricing rewards engagement—opened emails return as credits. If you have high open rates, this can significantly reduce costs. We don't have this model; all emails count toward your quota.

3. AI Delivery Optimization Is Critical

Netcore's Raman AI optimizes send times, predicts engagement, and manages throughput automatically. If you need AI-powered delivery intelligence, Netcore is purpose-built. Our AI generates content; theirs optimizes delivery.

4. You Need AMP for Email

Netcore supports AMP emails for interactive experiences (forms, carousels inside emails). If you need app-like experiences within email, Netcore offers this. We don't support AMP emails.

5. Asia-Pacific Delivery Matters

Netcore has strong infrastructure and presence in India and Asia-Pacific. If regional delivery to APAC is important, they have an edge.

Pricing at Every Scale

Emails/Month Sequenzy Netcore/Pepipost Difference
2,500 Free Free trial only Sequenzy has permanent free tier
15,000 $19/mo ~$25/mo Similar cost
60,000 $29/mo ~$25/mo Netcore cheaper (transactional only)
120,000 $49/mo ~$35/mo Netcore cheaper (transactional only)
300,000 $99/mo ~$65/mo Netcore cheaper (transactional only)
600,000 $199/mo ~$125/mo Netcore cheaper (transactional only)
1,200,000 $349/mo Custom pricing Contact Netcore for pricing

Netcore is cheaper for pure transactional email at volume, especially with their "opened emails free" pricing. But Sequenzy includes marketing automation, AI content generation, subscriber management, and Stripe integration — features you'd need separate tools for with Netcore.

Who Should Use Each Platform

Choose Sequenzy if you are:

  • A SaaS founder who needs marketing automation + transactional in one platform
  • Running a subscription business and want automated trial, churn, and upgrade emails
  • Looking for AI-generated email sequences to save time on content creation
  • Wanting Send Time Optimization to maximize email engagement
  • Needing subscriber management with lists, segments, and tags
  • A developer who wants one API for both transactional and marketing emails

Choose Netcore/Pepipost if you are:

  • An enterprise sending billions of emails monthly
  • Needing AI-powered per-contact delivery optimization (Raman AI)
  • Wanting the "opened emails free" pricing model to reward engagement
  • Targeting Asia-Pacific markets with strong regional delivery needs
  • Building AMP interactive emails for app-like experiences
  • Already have a separate marketing tool and just need delivery infrastructure

Real Setup Time

Task Sequenzy Netcore/Pepipost
Account creation 2 minutes 5-10 minutes
Domain verification 10-15 minutes 10-15 minutes
API integration 15-30 minutes 15-30 minutes
First transactional email 10 minutes 10 minutes
First marketing campaign 5 minutes (AI-generated) N/A (not available)
Subscriber management Built-in N/A (manage yourself)
Stripe integration 5 minutes (native) N/A (not available)
First automation 10 minutes N/A (not available)

For transactional email only, both are quick to set up. Sequenzy adds marketing capabilities that Netcore doesn't offer.

How to Migrate from Pepipost/Netcore to Sequenzy

Step 1: Set Up Your Sequenzy Account

Sign up at Sequenzy and connect your Stripe account. Configure domain authentication (SPF, DKIM, DMARC).

Step 2: Update Your API Integration

Replace Netcore API calls with Sequenzy's REST API. The transactional email API is straightforward — update the endpoint, authentication, and payload format.

Step 3: Build Your Marketing Layer

Since Netcore doesn't have subscriber management, import any contact lists you maintain separately. Set up segments, tags, and automation workflows in Sequenzy.

Step 4: Create Email Sequences

Use AI sequence generation to quickly create onboarding, trial, and lifecycle email sequences. This is new functionality you didn't have with Netcore.

Step 5: Test Deliverability

Run both platforms in parallel for 1-2 weeks. Compare delivery rates, open rates, and inbox placement. Verify that Sequenzy's deliverability meets your needs.

Step 6: Complete the Switch

Once satisfied with deliverability, point all transactional and marketing emails to Sequenzy and cancel your Netcore subscription.
