Sending SMS in the United States is not the same as sending SMS in Europe or LATAM. The Campaign Registry, brand vetting, throughput tiers, and carrier-specific filtering all sit between your code and the customer's lock screen. 4notify takes that work off your plate while keeping the API straightforward.
Each capability ships on the standard plan. Nothing in this list is an upsell or a separate product line.
We submit your brand to The Campaign Registry, file each use case (customer care, account notifications, marketing, MFA), and surface vetting scores so you know what throughput to expect on each carrier — no opaque 'pending' state for weeks.
If your volumes or content profile call for a toll-free number, we provision and verify it. Short codes are sourced through our T-Mobile and Verizon partners, with the lease, audit history, and quarterly content review included in the platform.
Carrier-mandated opt-outs are processed in real time. We store a per-recipient consent ledger with the source channel (web form, IVR, in-app), the wording the user agreed to, and a tamper-evident hash you can produce in an audit.
Two-factor codes route through low-latency carrier paths with sub-second median delivery. If a leg fails, we retry against an alternate carrier route rather than blindly resending — so codes don't arrive after the user's grace window.
Pricing is per segment with carrier surcharges shown line-by-line — no hidden 'fees' bucket on your invoice. Throughput, MPS tier and carrier delivery rates are visible inside the deliverability console covered later in this catalog.
REST and SMTP endpoints for receipts, password resets, and product alerts — built for US sender requirements.
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.
