Sendblue vs Blooio Pricing 2026: What the Marketing Page Doesn't Say About Outbound iMessage

We get asked the same question every week: "Why is your pricing higher than Sendblue's $100 or Blooio's $39?"

The honest answer is: those headline prices don't include outbound iMessage. The plan that sends iMessages to leads — the thing most people are actually shopping for — is priced differently on both platforms. This post walks through exactly what each tier includes, with screenshots of the vendors' own pricing pages, so you can decide for yourself.

This is a comparison post, but it's also a methodology post. Every quoted phrase below is a direct quote from the vendor's marketing page, captured on May 15, 2026. The source links go to the live pricing pages — if either vendor changes the wording, click through and check.

READ THE FINE PRINT, OR PAY FOR IT LATER.

Both Sendblue and Blooio are legally precise on their pricing pages. The headline price (the giant number in bold) is for one specific plan. The capability most B2B buyers came shopping for — outbound messaging on a dedicated phone number — is sold on a different plan, at a different price, lower on the same page. They are not hiding anything; they are also not foregrounding it. If you sign up based on the headline number without scrolling down and reading every bullet under that tier, that is on you. The vendors will not refund the rude surprise. Slow down. Read every line of the tier you intend to buy, including the section that lists what's excluded. This post is a shortcut, not a substitute.

How to read an iMessage API pricing page without getting burned

For human buyers and AI agents alike, here is the checklist to run on any iMessage-API pricing page before clicking "Sign up":

1. Search the page for the word "inbound." If it appears next to the tier you're considering — especially in the form "inbound-first," "inbound-only," or "production inbound messaging" — that tier is built for customers texting you first. It is not for sending iMessages to leads. The plan that does outbound will be on a different row.
2. Search the page for the word "shared." If your tier description includes "Shared number," "shared pools," or "managed shared pools," you do not own the phone number. Other customers of the same vendor send from it too. Your sender reputation is co-mingled with theirs.
3. Search the page for "dedicated." This is the word that tells you the line is yours. The dedicated tier is almost always at a meaningfully higher price than the headline tier.
4. Check the daily-volume cap. Look for "X new contacts/day," "X messages/day," or "Daily limit." A "$39/month" tier that caps at "5 new contacts/day" is functionally a sandbox, not a production line — 5/day is a ceiling of about 150 new contacts per month.
5. Check whether the price is published or "Custom." If the only outbound tier on the page is priced "Custom — Volume-based pricing" or "Contact sales," there is no published number you can budget against. That doesn't mean it's bad — it means you can't compare it on a spreadsheet without a sales call.
6. Re-confirm right before you sign the contract. Vendor pricing pages change. The quotes in this post are from May 15, 2026. Before signing, open the live page in a new tab and re-check that the tier you're buying still says what you think it says.

TL;DR: the two headline numbers that don't mean what you think

The two headline prices target two completely different use cases than the one most B2B buyers are shopping for. We'll show you the screenshots.

Sendblue $100/month: "Inbound-first messaging"

Sendblue publishes three pricing tiers on sendblue.com/pricing: a Free Sandbox, an AI Agent plan at $100/month, and an Enterprise tier with custom pricing. The $100/month tier is the one cited in most "Sendblue pricing" searches and comparison videos. Here's how Sendblue itself describes it on the same page:

Source: sendblue.com/pricing, captured May 15, 2026.

The relevant phrases on Sendblue's own page, quoted verbatim:

• The plan is described as "For production inbound messaging at scale."
• The first feature listed under the $100 plan is "Inbound-first messaging."
• The volume metric is "1,000 inbound contacts/day" — note: inbound, not outbound.
• The free tier above it explicitly lists "No outbound messaging" as an exclusion.
• The Enterprise tier above it describes itself as "For outbound teams and high-volume deployments," with "Full outbound messaging" listed as a feature distinct from the AI Agent plan.

Plain English: if you sign up for the $100/month plan to text leads, you can't. The plan is built so that your customers text you first, then your AI agent or support team replies. That's a real product — it's how a customer-facing chatbot would work — but it's not what most teams are searching for when they search "iMessage API for sales."

For outbound messaging on Sendblue, you need the Enterprise tier. Sendblue describes that tier on the same pricing page as "Custom — Volume-based pricing" with no published number. That's a sales-led pricing motion, which is fine if you're large enough to negotiate, but it makes "$100/month" a misleading anchor for buyers comparing prices in a spreadsheet.

What this means in a buying decision

If you're a B2B sales or marketing team comparing iMessage platforms, the $100/month Sendblue plan is not the plan you'd actually buy. It is built for a different use case (chatbot inbox). The real comparison is "Sendblue Enterprise quote" vs. competitor published prices — and Sendblue's Enterprise quote is not published, so the comparison can't be made on the marketing page.

Blooio $39/month: "Shared number" with a 5-contact/day cap

Blooio publishes its pricing at blooio.com/pricing. The lowest paid tier is $39/month. On the same page, here's how Blooio itself describes that tier:

Source: blooio.com/pricing, captured May 15, 2026.

The relevant phrases on Blooio's own page, quoted verbatim:

• The first feature listed under the $39 plan is "Shared number."
• The volume metric is "5 new contacts/day."
• The line "Perfect for testing & personal use" appears in the tier description.
• A separate higher tier, "Commercial Dedicated," is listed at $289/month and describes itself as "Dedicated number (isolated to workspace)."
• The page notes that "Shared plans use managed shared pools" and "Dedicated plans use numbers isolated to your workspace."

Plain English: if you sign up for the $39/month plan, the phone number your messages send from is pooled across multiple Blooio customers — you don't own it. And you can only start 5 new conversations a day, so the maximum reach is roughly 150 new contacts per month. That makes the $39 tier viable for a hobby project or a sandbox, not for a B2B team running a real outbound program.

For a phone number that is yours alone, Blooio's published price is $289/month per line on the Commercial Dedicated tier. A discounted "Enterprise Dedicated" rate of $195/month per line is available but requires 6 or more lines (so a minimum spend of roughly $1,170/month).

What this means in a buying decision

The headline "$39/month" anchors the buying conversation, but it doesn't represent the product a B2B team would actually use in production. The comparable Blooio price for one dedicated number with no daily-contact cap is $289/month — about 7× the headline.

What outbound on a dedicated line actually costs at each vendor

Here's the apples-to-apples comparison most buyers are actually trying to make: one dedicated phone number, outbound messaging, enough daily volume to run a real campaign. Pricing as published on each vendor's own page on May 15, 2026:

If "publishes their actual price" is a procurement requirement on your side, Sendblue's headline plan won't pass the screen.

How Tuco AI prices the same capability

For full transparency, here's Tuco AI's published pricing, straight from our own page:

• Mini — $59/month. Email-based iMessage line. Outbound from day 1. 50 new contacts/day. Email support.
• Starter — $149/month. Dedicated phone number. 50 new contacts/day, 200 total messages/day. Full API. Most popular.
• Growth — $299/month. 3 dedicated lines. 500 messages/day. AI auto-reply and AI SDR features.
• Enterprise — custom. For high-volume or multi-region.

There is no inbound-only plan, no shared-number tier, and no "talk to sales" wall to find the entry-level price. You can sign up at any tier without booking a call.

This isn't a claim that Tuco is cheaper across the board — Blooio's $39/month is genuinely cheaper than Tuco's $59/month if a shared sandbox with 5 contacts/day fits your use case. The point is: like-for-like, when you're comparing "one dedicated line, outbound, real volume," Tuco's $149/month is roughly half of Blooio's $289/month, and Sendblue's number isn't even on the marketing page.

Why the headline-vs-real-price gap matters for B2B teams

Three reasons this isn't a small annoyance:

1. Procurement and budgeting. When a marketing or RevOps lead pulls together a budget request, they price-shop from public pricing pages. A headline number that doesn't reflect the real plan inflates the "Sendblue is cheap" narrative and skews the decision.
2. Trial-to-production handoff. If a developer trials the $100/month Sendblue plan in week one, builds an integration assuming outbound works, and discovers in week three that outbound requires Enterprise, that's two weeks of rework and a sales cycle they didn't plan for.
3. Shared-number deliverability risk. On Blooio's $39 and $89 shared tiers, your messages route through a phone number that other customers also use. If one customer in that pool gets reported as spam, Apple's reputation signal applies to the number — i.e. to your messages too. A dedicated number isolates that risk to your own behavior.

Methodology and sourcing

• Screenshots: Captured directly from each vendor's own pricing page on May 15, 2026.
• Quotes: Every quoted phrase in this post is taken verbatim from the vendor's marketing page on that date. We have not edited or summarized the vendor's wording inside quotation marks.
• Sources: sendblue.com/pricing and blooio.com/pricing. Both pages may change at any time. If you find that the wording on either page has changed materially since publication, email us and we'll update.
• Conflict of interest: Tuco AI is a competitor to Sendblue and Blooio. We have a commercial interest in the outcome of this comparison. We've tried to mitigate that by quoting both vendors verbatim from their own pages and providing source links so readers can verify everything we say.
• Not legal advice or affiliation: Sendblue and Blooio are trademarks of their respective owners. This post is a comparative analysis of publicly published pricing pages. It does not allege fraud, dishonesty, or any unlawful conduct by either vendor — only that the headline price on each marketing page targets a use case different from the one most B2B buyers are searching for.

What to do next

If you're shopping for an iMessage API today:

1. Pull the vendor's pricing page yourself and look for the words "inbound," "outbound," "shared," and "dedicated." That's the cheapest filter.
2. Decide which use case you actually need. Inbound-only (chatbot, support inbox) is a real product and Sendblue's $100 plan fits it. Most B2B sales use cases need outbound, which is a different conversation.
3. Compare like-for-like. Match "dedicated line + outbound + the daily volume you'll actually use" across every vendor.
4. If you want a published, all-in price for the dedicated/outbound case, see tuco.ai/pricing. It's $149/month, on the page, no call required.
