Open-source alternative
for SendGrid
Pay-as-you-go instead of fixed subscriptions. No complex setup, no feature gating, no enterprise sales pitches. Built for developers, not procurement teams.
The Pricing Model That Makes Sense
Pay for what you use, not for what you might use
Pay per email sent
Pay-as-you-go pricing. Only pay for emails you actually send, no monthly minimums.
Monthly subscription tiers
Fixed monthly fees based on email volume tiers with feature restrictions.
Why Choose Plunk Over SendGrid
Built for modern developers, not enterprise sales teams
Simple, Transparent Pricing
Pay-as-you-go per email. No hidden fees, no complex tiers, no enterprise sales calls. Start free, scale as you grow.
5-Minute Setup
Start sending emails in minutes, not hours. Modern API, clear documentation, no complex configuration. Copy-paste and go.
Marketing Included
Campaigns, workflows, and segmentation at no extra cost. SendGrid requires their separate Marketing Campaigns product with additional fees.
Open Source & Transparent
AGPL-3.0 licensed. Inspect the code, contribute features, self-host if needed. No black boxes, no vendor lock-in.
Self-Hostable
Run on your infrastructure with Docker. Full data control, compliance-ready, cost-optimized. SendGrid is cloud-only.
No Feature Gating
All features available on all plans. No artificial limits, no forced upgrades to "enterprise" for basic automation.
