4notify's transactional email service is designed for the messages that have to land in the inbox: order receipts, password resets, two-factor codes, billing alerts, and operational notices. We hold every message to the same standard your customers expect from their bank or their iPhone — fast, signed, and free of marketing-style boilerplate that triggers spam filters.
Each capability ships on the standard plan. Nothing in this list is an upsell or a separate product line.
DMARC alignment, one-click List-Unsubscribe, and an automatic spam-complaint loop are configured the moment you verify a domain. We surface failing checks before they break delivery, so you don't learn about a rejected From: header from a customer ticket.
Start on a shared US-warmed IP pool with strict tenant isolation; graduate to a dedicated IP with an automated warm-up schedule once your volume justifies it. SPF, DKIM, BIMI, and MTA-STS records are generated for you and validated daily.
Send the same way you write the rest of your code. Idempotency keys make safe retries trivial during incidents, and per-message metadata lets you correlate sends to invoices, orders, or workflow runs without parsing logs.
MJML and Handlebars templates render in a sandbox that flags broken merge variables, missing alt text, and accessibility issues before a send is even queued — so a typo in a marketing rush never goes out to 50,000 customers.
Email sits next to SMS, WhatsApp, and webhooks in the same console, so a single notification policy can fan out across channels with retry rules and fallbacks. Pricing is per-message with no per-domain or per-template fee — you only pay for what leaves the platform.
10DLC, toll-free and short-code SMS for customer alerts, MFA, and field-service updates.
Official Cloud API access for utility, authentication, and customer-care conversations.
Fan-out, retries, and signature verification for outbound HTTP events that need to actually arrive.
Move beyond one-off sends. Trigger flows from product events, sequence messages across channels, and adapt copy to who is reading it.
Know what happened to every message — and why — without piecing it together from carrier exports and inbox screenshots.
