4notify vs Twilio
This comparison is for US teams choosing a way to send SMS, WhatsApp and email. Twilio is a communications platform billed per message. 4notify.net is a notification product with a panel, templates and an API, billed by plan. 4notify does not handle US carrier registration (A2P 10DLC), which matters for US SMS.
Feature comparison
| Feature | 4notify.net | Twilio |
|---|---|---|
| Pricing model | Monthly plans with separate quotas per channel. Plans at $55, $145 and $335 per month, plus a free email-only plan. When a quota is reached, sending is blocked; add-on packs raise it. There is no per-message overage billing. | Pay as you go: US SMS at $0.0083 per segment plus carrier surcharges; WhatsApp at $0.005 per message plus Meta's fees. |
| Channels | SMS, WhatsApp, email and push through one panel and one REST API (JWT, client credentials). WhatsApp starts on the Scale plan and uses your own Meta Business credentials. | SMS, WhatsApp, email (SendGrid), voice and video as separate products. |
| Templates and automation | Message templates, workflows and subscriber preferences. There is no campaign builder. | Build-it-yourself through APIs and SDKs. |
| US compliance | Not handled: 4notify has no A2P 10DLC brand or campaign registration. Inbound STOP replies are classified and opt the subscriber out of marketing SMS. | The customer registers brand and campaign (10DLC). Twilio's Help Center lists brand fees of $4.50 or $46 and a $15 one-time campaign fee plus monthly fees. |
| SMS routing | The default route is a provider relay run by 4b2b. You can instead send from your own Android phone (SMSGate) or through your own HTTP SMS provider; phone-sent SMS do not use 4notify credits. US SMS delivery coverage is not confirmed. | Global reach; US SMS prices and registration fees are published. |
| Trial | 14-day trial on the Grow and Scale plans. | Pay-as-you-go; trial terms on Twilio's site. |
| Best fit | Teams that want a working panel and predictable monthly quotas for notifications. | Developers who need global reach, voice and fine control. |
