$39/mo shared or $99/mo dedicated on current promotional pricing — the cheapest dedicated line in the category.
The tiers
Free Sandbox
$0no card required
- API testing and test messages
- Message Center preview
Catch Testing only — no live customer-facing number, so you cannot evaluate real deliverability on it.
Shared Number
$39per month, promotional (normally $78)
- A shared Miss Blue number
- Real conversations with customers
- Full API and Message Center access
- Promotional rate stated as locked in for the life of the account
Catch Beta usage limits apply to keep the shared line healthy, and a shared number means deliverability depends partly on other customers.
Dedicated
$99per number, per month, promotional (normally $198)
- A private number nobody else sends from
- Unlimited contacts and unlimited team seats
- API, integrations and the team inbox
- No per-message charges
Catch Miss Blue recommends a maximum of 30 new outbound conversations daily with a 30%+ rolling reply rate — a real ceiling if you are doing volume outbound.
Enterprise

- Guaranteed SLA
- Dedicated hardware
- Named account manager and migration support
- Multi-organisation discounts
Costs that are not on the pricing page
- A local number request is a **$205 one-time fee** — worth budgeting if the area code matters to you.
- Conversational AI is a separate add-on at **$100/mo plus a $250 setup fee**, not part of the base plan.
- The headline prices are promotional. The stated regular rates are $78 and $198, so price your renewal against those unless the lock-in is contractual.
- Unlimited team seats is genuinely unusual — most competitors charge per line, so a large front-desk team is cheaper here than the sticker suggests.
Miss Blue is priced unusually for this category in two ways, and both are worth understanding before you compare it to anything.
The dedicated line is the cheapest in the category
A dedicated number is the tier most businesses actually need — it is what stops another customer's sending behaviour affecting your deliverability. Miss Blue prices that at $99/month on current promotional pricing.
| Provider | Dedicated line | Note |
|---|---|---|
| Miss Blue | $99/mo (normally $198) | Promotional; unlimited team seats |
| Photon | $250/line/mo | Adds group messaging and mini apps |
| Blooio | $289/mo | Flat, unlimited messages |
| Sendblue | Quote only | Reported near $1,000/line plus setup |
Two things that are not in the headline price
A local number request is a $205 one-time fee, and conversational AI is $100/mo plus $250 setup. If either is part of your plan, price them in — the base figure is genuinely low but it is a base.
Unlimited seats changes the maths for non-technical teams
Most vendors in this category price per line and assume a developer is the only consumer. Miss Blue's Dedicated tier includes unlimited team access to the Message Center, which means a front desk of six people costs the same as one. For a salon, clinic or dealership where several staff answer messages, that is a materially different cost structure from a per-seat or per-line competitor.
The outbound guidance is a real constraint
Miss Blue recommends a maximum of 30 new outbound conversations a day, with a 30%+ rolling reply rate. That is sensible advice for line health — it is the same reasoning behind why providers throttle you — but if your use case is high-volume cold outbound, this is not the plan for it, and you should say so in the sales conversation rather than discover it later.
The free sandbox is testing-only with no live number, so unlike Photon's free tier you cannot use it to check real-world deliverability. Use it to build the integration, then pay for a line before you judge the channel.
The direct comparison against the best-known name in the category is Miss Blue vs Sendblue.

Best value for
Teams that need a shared inbox non-engineers can run as well as an API, and anyone who wants a dedicated line without paying $250–$289 for one.
