SendGrid has been a go-to email API for over a decade. But after the Twilio acquisition, many developers have noticed increasing complexity, opaque pricing, and a shift away from developer-first principles. If you're looking for a modern alternative, here's why developers are switching to Postject.

Why developers leave SendGrid

Complexity creep

What started as a simple email API has grown into a sprawling platform with marketing campaigns, design editors, and contact management. For developers who just need to send transactional emails, the interface and API have become unnecessarily complex.

Pricing confusion

SendGrid's pricing page requires a calculator to understand. Base plans, add-ons for dedicated IPs, extra charges for email validation, separate pricing for marketing vs transactional -- it adds up fast and unpredictably.

Support challenges

Ticket-based support with long wait times is a common complaint. When your email delivery breaks at 2 AM, waiting 24-48 hours for a response isn't acceptable.

What Postject offers instead

Clean, focused API

Postject's REST API is designed for email sending, period. No marketing campaign builder, no contact management, no feature bloat. The API is well-documented, consistent, and works the way developers expect.

5-minute quickstart

Create an account, verify your domain, get an API key, send an email. The entire setup takes under 5 minutes. Compare that to SendGrid's multi-step configuration process with sender authentication, IP warmup plans, and suppression group setup.

Transparent pricing

Four simple plans with clear limits:

Free: $0/mo -- 100 emails/day
Starter: $10/mo -- 10,000 emails
Pro: $19/mo -- 50,000 emails, all features included
Enterprise: $120/mo -- 500,000 emails

No add-ons. No hidden fees. Inbox placement visibility and content analysis are included in every plan.

Built-in deliverability tools

SendGrid charges extra for inbox placement testing and email validation. Postject includes content analysis (spam score, HTML quality, link safety) in every plan. You can check your email before sending and fix issues proactively.

Modern developer tooling

Beyond the API, Postject provides:

CLI tool: Send emails, tail logs, manage servers from the terminal
MCP server: Connect AI assistants to your email infrastructure
SDKs: Node.js, Python, PHP, Ruby, Go
Webhooks: Real-time events with HMAC verification

Migration from SendGrid

Switching from SendGrid to Postject is straightforward:

Create a Postject account and verify your sending domain
Replace the SendGrid SDK calls with Postject's API or SDK
Update webhook endpoints to receive Postject events
Test in sandbox mode, then go live

The REST API patterns are similar, so most integrations can be migrated in an afternoon.

Who should switch?

If you're a developer or engineering team that primarily sends transactional emails and wants a clean, predictable, and well-priced API -- Postject is built for you. If you need a full marketing automation suite with campaign builders and contact management, you may want a marketing-focused platform.
