Sendblue Pricing in 2026: Full Breakdown
TL;DR
As of August 2026, Sendblue publishes three tiers: a $0 sandbox, an AI Agent plan at $100 per line per month that is inbound-first with 1,000 inbound contacts a day, and a custom-priced Enterprise tier. Full outbound messaging sits only on Enterprise, so if you are pricing cold outreach, the $100 headline is not your number.

What does Sendblue cost in 2026?
As of August 2026, Sendblue publishes three tiers: a $0 Free Sandbox, $100 per line per month AI Agent plan, and custom Enterprise pricing. Full outbound messaging is Enterprise-only.
The $100 AI Agent plan is inbound-first. If you are pricing cold outreach, that headline number does not cover it: the outbound capability most sales teams shop for requires an Enterprise quote.
| Plan | Price (August 2026) | Scope | Key limits |
|---|---|---|---|
| Free Sandbox | $0 | Testing, inbound-first | Shared number, up to 10 verified contacts |
| AI Agent | $100/line/mo | Production, inbound-first | 1,000 inbound contacts/day per line |
| Enterprise | Custom quote | Full outbound messaging | Multiple lines, account manager |

Production inbound-first
What does the $100 AI Agent plan include?
Sendblue's $100 includes a dedicated number, 1,000 inbound contacts a day, webhooks, media, typing indicators, and priority support. Unlimited messaging per line, metered only by daily contact limits to prevent spam.
Fallback is handled cleanly: no iMessage means automatic RCS, then SMS, from the same number at no extra charge.
Sendblue does not support message blasts at all, by policy. Number porting is available but adds 3 to 5 days to setup.
- No per-message fees, no carrier surcharges, no A2P registration required
- Automatic RCS then SMS fallback from the same number at no extra charge
- No message blasts on any tier, by policy
Why can't outbound teams price Sendblue from the website?
The outbound tier is quote-only, which is a standard move in this category called the quote wall. Sendblue publishes a $100 number, holds the outbound price for the sales call.
The Enterprise tier lists full outbound messaging, multiple dedicated lines, and a dedicated account manager, with volume-based pricing and no number attached.
Tuco AI (May 15, 2026) estimates Sendblue Enterprise at $12,000/year, though that's a rival's claim. Sendblue publishes: outbound costs more than $100/line/month.
Sendblue's inbound posture and compliance depth
Sendblue is inbound-first: AI support agent, concierge, or reply-heavy nurture at $100/line/month. No setup fee, month-to-month, sandbox before paying.
Developer tooling: Node.js, Python SDKs, CLI, self-serve signup.
The tradeoff is the quote wall on outbound: the $100 plan will not support cold outreach, and the tier that does carries no published price.
Comparing pricing: inbound versus outbound
Blue Reacher prices outbound plainly: $199/mo or $1,949/yr ($162.50/mo annual). Unlimited iMessages, 50 opted-in / 30 cold daily, no A2P, white-glove.
Replies are never metered.
The $100 AI Agent plan is inbound-only. For outbound sales, compare Blue Reacher's published rate against a Sendblue Enterprise quote; no benchmark number exists.

The Five Pages That Tell You If a Vendor's Numbers Hold Up
Most buyers read one page before a demo, and it is the pricing page. Five pages exist on nearly every messaging vendor's site, they get updated on different days, and when two of them disagree the disagreement is the most useful thing you will find all week. Here is the read order, with live contradictions dated 16 September 2026.
Per-Message Texting Bills You in Credits, Not Messages
Every per-message texting quote you have been given prices a unit called a credit. A credit is a 160-character segment, an emoji cuts it to 70, and picture messages cost three. The definition almost never appears on the pricing table. Read from vendor and carrier pricing pages on 10 September 2026.
