Sendblue alternatives: six iMessage APIs worth comparing

Most people looking for a Sendblue alternative have hit one of two walls — the published plan cannot send outbound, or the enterprise quote came back too high. Both have good answers.

The verdict

Blooio is the direct answer for most people leaving Sendblue on price: $39/month flat, outbound included, no sales call. Photon is the better fit if you are building an agent and want a free tier to evaluate on. Linq is the one to move to if compliance rather than cost is the problem.

Sendblue is the name most people find first, and there are two common reasons they start looking elsewhere. Which one applies to you determines which alternative is right.

Reason 1 — the price

  • The $100 plan turned out to be reply-only
  • Outbound needs an enterprise quote
  • Reported ~$1,000/line plus a reported $2,000 setup
  • You wanted to launch this month, not next quarter

Reason 2 — the fit

  • You need SOC 2 for a security review
  • You need RCS, SMS or voice in the same API
  • You want a free tier to evaluate on
  • You need a CRM integration that already exists

The alternatives, ranked by who they suit

Switching is easier than you expect, if you prepared for it

Every provider in this category is a POST with a phone number and a body. If you wrapped the vendor behind your own send() function, migrating is an afternoon. If you did not, do it as part of the move — switching providers.

What to check before you move

  1. Can you keep your number? Ask both vendors in writing. A number change means telling every customer, which is the real cost of switching.
  2. Does the new plan actually do outbound? The mistake that sent you looking is easy to repeat.
  3. Does it fall back to SMS? If half your customers are on Android, this is not optional.
  4. Run both in parallel for a week. Cheap insurance, and it surfaces deliverability differences that a demo will not.
