Stop renting your messaging.

A mid-size agency sending 40,000 messages/month pays Twilio $1,580. That same month on Simsendly: $297 flat. You keep the rest.

Agencies who switched

Built by agency operators, for agency operators.

We run opt-in campaigns for dozens of clients. Twilio's 10DLC approval was killing our launch timelines — sometimes three weeks just to get a campaign approved. With Simsendly, we paired phones in 20 minutes and clients were sending the same day. Deliverability is actually better.

CMO, Optinify

3-week delay → live in 20 min

Our clients use GoHighLevel for everything. When we layered Simsendly as the SMS engine, follow-up rates on trial-to-paid conversions jumped from 12% to 28%. The iMessage channel is the killer feature — SaaS users are iPhone-heavy and they actually respond.

Field service is all about speed. A technician dispatched via Simsendly arrives faster because the message goes through the carrier instantly, not a vendor queue. We run devices across our whole client base and reliability has been flawless — zero missed dispatches in three months.

FAQ

Questions operators actually ask.

No OAuth, no carrier paperwork, no A2P 10DLC. You install the Simsendly companion app on a phone you already own. Messages are sent natively from that device using its own SIM. The carrier sees the phone, not us.

iMessage throughput is gated by Apple, not by us. In practice a single Mac+iPhone pair can comfortably send 60–90 iMessages per minute sustained. For higher throughput we pool multiple devices and route across them automatically.

You link your existing WhatsApp Business number on a dedicated device. Simsendly routes outbound messages through that device and pulls inbound replies into your GoHighLevel inbox. No meta approval process, because you are the approved business.

You remain the sender of record — you control consent, opt-in, and opt-out flows exactly as you do today. Simsendly honors STOP / UNSUBSCRIBE automatically and surfaces opt-out status in the dashboard and in GoHighLevel. Compliance responsibility is yours; we make it easy to enforce.

Simsendly detects offline devices in under 15 seconds and reroutes queued messages to a fallback device or channel based on your routing rules. You get a dashboard alert and an optional webhook. Nothing sits in limbo.

On the Scale plan, yes. Sub-accounts can be presented as your branded domain (messaging.youragency.com) with your logo and colors. On Agency, clients see a Simsendly-branded read-only view.

Most operators start with phones they already have on hand: Pixel 6/7/8, iPhone 12 or newer, plus any Mac for iMessage relay. For higher volume we recommend a dedicated Android SIM farm — we can introduce you to a few trusted suppliers.
