These Are Different Tools

Let's be clear upfront: Postmark and Sequenzy solve different problems.

• Postmark is a transactional email specialist. It's laser-focused on getting your password resets, receipts, and notifications delivered instantly with excellent deliverability.
• 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 a sports car to an SUV. Both are vehicles, but they're optimized for different things.

When should you choose Sequenzy?

1. You Need Marketing + Transactional in One Platform

If you're using Postmark for transactional emails, you'd need a separate tool (Mailchimp, ConvertKit, etc.) for marketing campaigns and automation. Sequenzy combines both in one platform—one dashboard, one integration, one bill.

2. You Want Email Automation

Postmark doesn't have email sequences or automation. They explicitly state they don't offer "WYSIWYG email campaigns, scheduling tools, automated follow-ups, or A/B testing." If you need a welcome series, drip campaigns, or triggered sequences, you need Sequenzy or similar.

3. You Want Subscriber Management

Postmark is API-only for sending. There's no subscriber database, no lists, no segments, no profiles. You manage all that in your own application. Sequenzy gives you a full subscriber management system with tags, segments, and custom fields.

4. You Need Stripe Integration

Sequenzy connects directly to Stripe—syncing customer data, subscription status, MRR, and churn signals. Postmark is payment-agnostic and doesn't integrate with billing systems.

When should you stick with Postmark?

1. You Only Need Transactional Emails

If your use case is purely transactional—password resets, order confirmations, shipping notifications—and you're handling marketing elsewhere, Postmark is purpose-built for this. It's what they do, and they do it exceptionally well.

2. Deliverability Is Your #1 Priority

Postmark is famous for deliverability. They reject bulk/marketing senders to protect their reputation. If your transactional emails absolutely must arrive instantly (like 2FA codes), Postmark's focus is an advantage. We have good deliverability, but Postmark is the specialist.

3. You Already Have a Marketing Tool You Like

If you're happy with ConvertKit, Mailchimp, or another marketing platform and just need a transactional email service, Postmark + your existing tool might be the right combo. Don't switch if it's working.

4. You Need Inbound Email Processing

Postmark can receive and parse incoming emails—useful for support systems, reply handling, and email workflows. We don't support inbound email.

5. You're Cost-Sensitive for Pure Transactional

Postmark starts at $10/month for 10,000 emails. If you're only sending transactional emails and don't need marketing features, that's cheaper than our $49/month.

Honest Limitations of Sequenzy

• Not transactional-specialized: Postmark is laser-focused on transactional speed. We're a generalist.
• No dedicated IPs: High-volume senders might want Postmark's dedicated IP options.
• No inbound email: We can't receive and parse incoming emails.
• More expensive for pure transactional: $49/mo vs Postmark's $10-50/mo if you only need transactional.
• No landing pages: We don't have a landing page builder.

Honest Limitations of Postmark

• No marketing automation: No sequences, no drip campaigns, no triggered emails based on segments.
• No subscriber management: No lists, segments, or profiles. API-only.
• No WYSIWYG builder: Templates only, no visual campaign builder.
• No list uploads: You can't import a list of contacts and send a campaign.
• No A/B testing: Not available.
• Requires separate marketing tool: You'll need another platform for marketing emails.
