Notify product offering

Product offering

Core offering

Notify provides a minimal transactional email API for developers, centered on a single REST POST endpoint that accepts to, from, subject, and message fields for sending transactional emails such as password resets, magic links, onboarding sequences, notifications, and receipts. The product surface is deliberately stripped back to sending plus observability — domain verification (SPF/DKIM/DMARC), email delivery logs, webhooks for real-time events, and an automatic suppression list — with no template builders, drag-and-drop editors, or marketing automation features.

Product overview

Notify is a minimal transactional email API for developers — a single unified product focused on sending transactional email and observing delivery. The core offering consists of the Email API endpoint (POST /api/email/send), domain verification for SPF/DKIM/DMARC authentication, email logs for delivery tracking, and webhooks for real-time event notifications (available on Pro and Scale tiers). A suppression list protects deliverability. The product intentionally excludes template studios, drag-and-drop builders, and marketing automation features. Three pricing tiers provide scaling: Free (1,000 emails/mo), Pro ($10/mo for 10,000 emails), and Scale ($50/mo for 100,000 emails).

Products and services

Email API REST API for sending transactional email via a single HTTP POST call. Accepts to, from, subject, and message (HTML or plain text up to 100,000 characters). Delivers password resets, onboarding emails, notifications, and receipts for developers and technical teams building applications.
Domain Verification DNS-based SPF, DKIM, and DMARC verification service that allows production sending from custom from-addresses. Verified apex domains also cover subdomains for sending. Setup guides provided for Cloudflare and Route 53.
Email Logs Dashboard and API access to view delivery status, opens, clicks, bounces, and complaints for every sent message. The Email Logs API (GET /api/email/logs) returns event timelines filtered by event type, date range, and pagination. Retention is 48 hours on Free and permanent on Pro/Scale.
Webhooks Push email event subscriptions scoped to a verified sending domain for real-time delivery of Send, Delivery, Open, Click, Bounce, Complaint, and DeliveryDelay events. Up to 3 webhooks on Pro plan and up to 10 webhooks on Scale plan; not available on Free.
Suppression List Automatic suppression list that blocks any future sends to addresses that previously hard-bounced or generated complaints, protecting the customer's sender reputation and deliverability.

Notify competitors and assessment

Company assessment

Direct peers

Resend: Developer-focused transactional email API explicitly named by Notify as a primary competitor. Both target the same audience of developers seeking minimal API-first email infrastructure, with similar positioning around simplicity versus legacy ESPs.
Postmark: Transactional email service owned by ActiveCampaign, listed by Notify as a direct comparison target. Postmark serves the same developer/transactional-email use case and competes on deliverability and simplicity.
Mailgun: Email API service owned by Sinch, explicitly listed by Notify as a comparison target. Mailgun serves transactional and bulk email senders via REST API, overlapping directly with Notify's core offering.
SendGrid: Twilio-owned email platform that Notify explicitly positions against. SendGrid offers transactional and marketing email via API, with a much broader feature surface but higher complexity that Notify's minimalism targets as a wedge.
SparkPost: Email delivery platform focused on transactional and high-volume sending via API. Operates in the same developer/transactional email space as Notify, with similar emphasis on deliverability and observability.
Customer.io: Developer-oriented messaging platform with transactional email, in-app, and push notification capabilities. Overlaps with Notify's notification use cases and shares a developer-first product philosophy.

Broad incumbents

Amazon SES: AWS's commodity email-sending service, which Notify is built on top of and explicitly compares against. SES is the underlying infrastructure layer Notify abstracts, and developers self-hosting SES directly represent Notify's primary substitute.
Mailchimp Transactional (Mandrill): Mailchimp's transactional email add-on (formerly Mandrill). Provides SMTP/API transactional sending as an extension to Mailchimp's broader marketing platform, comparable to Notify's transactional API positioning.
Brevo: Email marketing and transactional platform (formerly Sendinblue). Provides transactional email API alongside marketing automation, representing the broader ESP category Notify positions against with its minimal-API stance.

Emerging players

Knock: Notification infrastructure API for product teams, with cross-channel support including email. Targets a similar developer audience building notification-heavy applications, with a broader channel mix than Notify.
