Engagespot

Engagespot is a notification infrastructure platform for in-app, email, push, WhatsApp, Slack, Discord, and webhook channels. Its pricing counts event triggers rather than every configured channel, which makes it easier to model than some delivery-count plans.

Judged purely as an API. What the request contract guarantees on retry, how complete the webhook event coverage is, whether suppressions are readable and writable programmatically, and how much the message log retains when something needs debugging in production.

Against high-frequency programmatic sends where a missed delivery is a product failure, Engagespot covers webhook coverage, event stream, the suppressions API, batch sending, and SDK breadth, and does not cover idempotency keys. Whether that gap matters depends on how central those are to the build.

• Best published rate per 1,000: Tiers not published in comparable form
• Batch sending: Yes
• SDKs: node
• Deliverability: Depends on the connected downstream providers for email, SMS, and other delivery channels.

Product teams that want predictable notification trigger pricing across many channels.

Teams that need a very low-cost paid step after the free tier.
