What 1, 5 and 10 lines cost
Published monthly prices. WhatSnap BYOP figures are software only; Sendblue's include its hosted hardware. WhatSnap BYOP is $29/mo per GHL Subaccount with 1 Line included, plus $15/mo for each extra Line in the same Subaccount. It excludes your own devices and carrier plans.

| 5 Lines | $89/mo | $500/mo |
| 10 Lines | $164/mo | $1,000/mo at list price |
- WhatSnap BYOP prices are software only. You buy and run your own devices (a Mac and an iPhone per iMessage Line, an Android phone per SMS Line) and pay your carrier directly.

Sendblue's Mac Mini or your own iPhone
Sendblue's pitch: no Apple hardware on your side. Per its blog, it operates Mac Minis in secure data centers, gives each paying customer dedicated Apple hardware resources and, in what it calls the rare event an account hits friction, handles “rotation and recovery” behind your line. The number is provisioned on Sendblue's platform. Sendblue's own blog says it is yours “for as long as you maintain your account.”
That is the trade. Per Sendblue's Terms, port-out costs $60 per line and is processed while you are subscribed. Once the subscription ends, the number goes back to the upstream carrier. And the published $100 plan is inbound-first: contacts text you first. Full outbound messaging sits on a custom-priced Enterprise plan.
WhatSnap BYOP flips it. The Mac and the iPhone are yours, the number sits on your SIM, and your Line can text a new lead first, paced inside warm-up and Apple's limits. Sendblue's blog lists “single point of failure” as the risk of running your own Mac. Fair question. On BYOP, if a device dies, you connect a new one under the same Apple ID and the Line resumes, with your GHL routing intact. Until then, delivery pauses and WhatSnap queues messages for up to 24 hours.
The line lives in your rep's pocket, not in someone else's rack
With BYOP, WhatSnap connects iPhones, Macs and Android phones you own to GHL. Your workflows send from your number. On an iMessage Line, your rep holds the iPhone. Here is what that changes for sales and marketing teams.
Your number, your Apple ID
On BYOP, the number, the SIM, the Apple ID and the carrier plan belong to you, not to us. If you leave WhatSnap, you lose the GHL connection; the phone, the number and the Apple ID stay with you.
The iPhone stays in your rep's pocket
On an iMessage Line, the iPhone is a real phone on your own carrier plan, paired with a Mac on the same Apple ID. When a text thread needs a voice, the rep can call the lead from the same number, on that iPhone. It is an ordinary call on your carrier line, placed from the phone, not from GHL. Carriers set their own rules for calls too, so the same spam-labeling risks apply to any number.
Reply from the phone
On an iMessage Line, the rep picks up the iPhone and replies, or records a voice note, right in Messages. The conversation keeps syncing to GHL, so your team sees the thread there too.
Leads may already know the number
Connect a mobile number your leads already have saved, and your message arrives from a contact they know. With Apple's Share Name and Photo turned on, iMessage can also show your name and photo.
You pay us for software, not hardware
$29 a month per GHL Subaccount, with 1 Line included. Each extra Line in the same Subaccount is $15 a month: 5 Lines come to $89, 10 Lines to $164. No per-message fees from WhatSnap. These prices exclude your devices and carrier plans: you buy the devices (or rent a cloud Mac) and pay your carrier directly.
Grow at your pace
Add a Line when you add a rep: $15 a month in the same Subaccount, plus the devices and carrier plan for that Line. There is no platform cap on Lines per agency, and each Line builds its own reputation. Keep a mobile number you already use, area code and all. Or port one onto your SIM, or get a new number from the carrier you choose.
What you take on with BYOP
Owning the line means running the devices. Here is what that takes, in plain terms.
iMessage Line: a Mac on macOS 11 or later (your own, or one you rent in the cloud; the iPhone, number and Apple ID stay yours) plus an iPhone with an active carrier plan, both signed into the same Apple ID.
SMS Line: an Android phone on Android 9 or later, with a SIM on an active SMS plan.
WhatsApp: connects by QR code, from Linked Devices on the phone that runs WhatsApp or WhatsApp Business.
Devices stay powered, online and awake. Keep the Mac, and an Android SMS phone, plugged in on stable Wi-Fi. If a device drops offline, delivery pauses, and WhatSnap queues messages for up to 24 hours; after that, they are marked failed.
A fresh Line warms up over 14 days. A number with history and inbound traffic may not need a formal warm-up, but our Acceptable Use Policy's first-14-day pacing still applies unless we confirm otherwise in writing.
Apple watches how many brand-new conversations each Apple ID starts. Providers typically keep it near 50 a day per line: our Acceptable Use Policy allows up to 50 new recipients a day per Apple ID in a new Line's first 14 days, and Sendblue's and Linq's docs use the same figure. Apple's rules are the same for every provider; the difference is who owns the line.
Apple and your carrier set their own rules and can act on any line, so we do not promise immunity. WhatSnap is built for leads who expect to hear from you, not for cold outreach at scale.
Devices and carrier plans are on you: hardware you buy once (or a Mac you rent in the cloud), a monthly carrier plan you pay directly, and power and internet to keep the devices online.
When Sendblue may fit better
You want no hardware on your side. Sendblue runs dedicated Apple hardware resources for each paying customer. If that is your main reason, WhatSnap does this too: our managed plans run the device for you, from $77/mo per line. See the pricing page.
You are building a product or an AI agent on an API. Sendblue leads with developers: a free sandbox, a CLI and SDKs, plus API features such as contact cards and FaceTime calling on a purchased FaceTime line.
Most of your volume is inbound, or you need compliance certifications. Sendblue's AI Agent plan takes up to 1,000 inbound contacts per day per line, Sendblue says it is SOC 2 Type II certified, and its Enterprise plan lists HIPAA.
Moving from Sendblue to WhatSnap BYOP in five steps
Decide on the number before you cancel
Per Sendblue's Terms, port-out requests are processed while your subscription is active, at $60 per line. Once it ends, the number returns to the upstream carrier and can no longer be ported out. To keep it, port it to a carrier SIM you own and keep Sendblue active until the port completes. Otherwise, before you cancel, tell active leads your new number from your Sendblue line, then start the new Line on its warm-up.
Set up your devices
For iMessage, a Mac on macOS 11 or later (yours or cloud-hosted) and an iPhone with an active carrier plan, both on the same Apple ID. For SMS, an Android 9+ phone with a SIM. WhatsApp connects by QR code. Follow Connect your first line.
Connect WhatSnap to GHL
Install WhatSnap from the GHL Marketplace, set P2P Messenger (WhatSnap) as the telephony provider in each Subaccount, and add your Lines. Replace Sendblue's own steps with GHL's native ones: Send iMessage becomes Send SMS, and Sendblue's Wait for Reply becomes GHL's Wait for Reply. Rework Check iMessage branches, since the iPhone falls back to SMS from the same number on its own. Move workflows that start on Sendblue triggers, such as Sendblue: Receive iMessage, to GHL's native reply triggers.
Save your history, then carry over opt-outs
Before you cancel, save any conversation history and contact details you need that live only in Sendblue. Per Sendblue's docs, messages sent through its API do not sync to other platforms automatically, so they may not be in GHL. Then mark every contact who opted out on your Sendblue number as DND in GHL before any workflow fires.
Warm up, then scale
Fresh Lines warm up over 14 days. A ported number that already gets inbound messages may not need a formal warm-up. Start with leads who have already replied, and keep first messages short and plain to lower the odds they land in the iPhone Spam folder.
Frequently asked questions
Is there a Sendblue alternative that works inside GHL workflows?
Yes. WhatSnap runs inside GHL as the telephony provider, so native Send SMS, Wait for Reply and GHL AI bots send through your own Lines: iMessage from a Mac and an iPhone, SMS from an Android phone, plus WhatsApp and Twilio. Replies sync back into the GHL conversation. On BYOP, the number stays on your SIM.
How much does WhatSnap cost compared with Sendblue?
On published prices, WhatSnap BYOP software costs less per line than Sendblue's AI Agent plan, before your own devices and carrier plans. WhatSnap BYOP is $29/mo per GHL Subaccount with 1 Line, plus $15/mo per extra Line in that Subaccount: $89 for 5 Lines, $164 for 10, software only. Sendblue's AI Agent plan is $100 per line per month with the hardware on Sendblue's side, per Sendblue's pricing page as of October 22, 2026. That plan is inbound-first, and Sendblue's full outbound plan has no published price.
Do I need my own iPhone and Mac to use WhatSnap?
On BYOP, yes, for iMessage. That is the core difference from Sendblue, which supplies the hardware. Each iMessage Line needs a Mac on macOS 11 or later, yours or cloud-hosted, and an iPhone with an active carrier plan, both on the same Apple ID. SMS Lines run on an Android 9+ phone with a SIM, and WhatsApp connects by QR code. Devices stay powered and online. Rather not run devices? WhatSnap also offers managed plans, from $77/mo per line: WhatSnap provides and operates the iPhone, on a number WhatSnap provides. See both options on the pricing page.
What happens when a lead does not have iMessage?
The iPhone falls back to SMS from the same number, as long as it is powered on with an active carrier plan. Voice messages are not delivered over SMS. Per Sendblue's site, Sendblue falls back to RCS (on V2 lines, per its docs), then SMS, from the same number at no additional charge.
Will my GHL workflows keep working if I switch from Sendblue?
Workflows built on GHL's native actions typically keep working. Once WhatSnap is the telephony provider, Send SMS, Wait for Reply and GHL AI bots route through your Lines. Replace Sendblue's own steps with GHL's native ones: Send iMessage becomes Send SMS, and Sendblue's Wait for Reply becomes GHL's Wait for Reply. Rework Check iMessage branches: that action is a lookup, not a send, and the iPhone falls back to SMS from the same number on its own. Move workflows that start on Sendblue triggers, such as Sendblue: Receive iMessage, to GHL's native reply triggers. List them all before you cancel Sendblue.
Can I call a lead or send a voice note from the same line?
Yes. On BYOP, the Line is your rep's own iPhone on your carrier plan, so they can call the lead from the same number. They can also reply or record a voice note right on the phone, and the conversation keeps syncing to GHL. From workflows, WhatSnap sends iMessage voice messages through a webhook. GHL voice calls themselves still run on Twilio or LeadConnector.
Put the line in your rep's pocket
Open a free demo account and start testing right now, with one limited Line and no credit card. When you are ready, move to BYOP and send from your own number in GHL. On an iMessage Line, your rep can reply from the iPhone, and the conversation keeps syncing to GHL. Add Lines as the team grows: $29 a month per GHL Subaccount with 1 Line included, $15 a month for each extra Line in the same Subaccount. Devices and carrier plans not included.
