BlueSendr is a macOS app that connects Messages on your own Mac to your CRM, so texts to your iPhone number show up in the CRM and replies typed there go out as iMessages. It installs as a LeadConnector (GoHighLevel) marketplace app. The software is licensed by Dominate Local LLC dba BlueSendr.
$49/month billed annually for one business connection with unlimited messages. A limited-time lifetime license costs $500 one time for three connections and one year of updates. You also need a Mac and an iPhone line.
Linq runs managed lines on its own infrastructure, with a REST API, SDKs and webhooks, and reaches GoHighLevel through Linq Blue. BlueSendr runs on a Mac and phone line you supply and documents no developer API. Linq Pro starts at $260/month; BlueSendr is $49/month billed annually. Linq falls back from iMessage to RCS and SMS; BlueSendr's SMS fallback depends on your iPhone's settings. Linq states SOC 2 Type II; BlueSendr publishes no certifications.
GoHighLevel agencies and small sales teams that already have a Mac and a phone line and want iMessage inside the CRM inbox, without needing an API.
BlueSendr supports 14 of the 77 features compared on Linq Alternatives.
