Where Sendblue beats Linq Blue
Sendblue publishes more than Linq. The $100 inbound plan is a real number you can budget, the free sandbox needs no credit card, and outbound caps are in print. G2 4.8 across 65 reviews, plus HIPAA plans.
- One 2026 fact cuts the other way. Sendblue disclosed a security incident on 5 August 2026: unauthorized access to records including content and phone numbers on 7 and 10 July. Bring this to your security review.
- Published pricing and published caps, against a quote-only product
- The category's only real review base: G2 4.8 across 65 reviews (July 2026)
- HIPAA plans and enterprise BAAs available
- A free sandbox with full API access, so evaluation costs an afternoon
Where Linq Blue beats Sendblue
Linq Blue is shaped like the job a sales team has. The product sends from HubSpot, Salesforce, and GoHighLevel with an install-once path that keeps existing SMS workflows intact.
- The balance sheet is the other edge. $27M raised, a $20M Series A in February 2026, and around 1,000+ teams claimed. If procurement scores vendor stability, Linq scores best.
- The February 2026 raise came with a public shift toward AI-agent infrastructure, so ask what ships for sales teams next.
- Sales-first product shape: CRM install, not an endpoint to wrap
- iMessage, RCS, SMS, and voice with transcription under one contract
- The strongest funding position in the niche: $27M raised
The pricing question neither answers in public
Outbound pricing is unpublished at both vendors. Sendblue's Blue Ocean is quote-only; Linq publishes neither. Third-party reports put Linq Blue between $160 and $250 per line per month.
- Ask both vendors: per-line rate, setup fee, daily caps, contract term. Neither answers in print. At Sendblue the printed part is the ceiling: 50 new contacts per line per day.
Those are our assumptions. The Blue Funnel Map runs the same arithmetic on the funnel you actually have, and you keep the map either way.

How to choose between Sendblue and Linq Blue
Sendblue or Linq Blue resolves fastest on buying process and stack shape, in that order.
- Reply-rate claims will not settle it: both vendors publish performance numbers of their own, and a two-week pilot on your real list beats every marketing page, this one included.
- Building on an API or shipping an AI agent, with a developer free to own sequencing and reply handling? Sendblue, and start in the sandbox today.
- Blocked in procurement on a certificate, with a CRM-shaped rollout to run? Linq Blue fits that motion better out of the box, at a per-line rate you first see in the quote.
- Need HIPAA paperwork? Sendblue advertises it, Linq does not.
- Betting on an 18-month roadmap? Ask Linq what ships for sales teams after the AI-agent refocus, and ask Sendblue how Blue Ocean caps scale with your list. Get both in writing.
- Running cold outbound and need a price today without a call? Neither publishes one, and the only outbound number in print here is Sendblue's ceiling of 50 new contacts per line per day; that is what the third column is for.

Can Sendblue or Linq Blue send cold outbound?
Both gate it behind sales. Sendblue's llms.txt says the $100 plan cannot message contacts who have not texted first. Its Blue Ocean outbound caps 50 new contacts per line per day with 200 follow-ups. Linq publishes no terms. Neither provides published pricing and caps you can check before a call.
Do either of these require A2P 10DLC registration?
No. iMessage does not run on the carrier SMS routes that A2P 10DLC governs, so no A2P registration is required at Sendblue, Linq Blue, or Blue Reacher. TCPA and consent obligations still apply on every channel, so keep a lawful basis for contact and a working opt-out regardless of vendor.
