THE REVIEW INDEX
Choose the agent’s messaging layer.
Sender direction, operator handoff and infrastructure ownership across ten options.
Miss Blue
An agent line with an operator close by
Miss Blue is our featured choice for a business agent that needs a dedicated number, project-scoped access and a shared place for people to take over. Its API and MCP paths support bringing your own agent into the messaging workflow.
$99/line/month promotional rateOpen review ↗Managed API · 02Sendblue
An inbound-first agent with a clear upgrade question
Sendblue’s named AI Agent offering starts with a dedicated inbound-first line and webhook access. It is a relevant option when the customer opens the conversation and the application mainly answers.
$100/line/month inbound; outbound quotedOpen review ↗Managed API · 03Linq
A messaging channel for a client-centered agent
Linq publishes both a messaging API and an official Claude Code iMessage channel. It can fit an agent whose working environment is that client and whose architecture needs the documented channel actions.

Choose the agent’s initiation rights before its tools
Blooio offers shared, dedicated and inbound-only plans alongside a documented MCP endpoint. That variety can support different agent prototypes, provided the sender model is chosen explicitly.
$89 shared / $289 dedicated per monthOpen review ↗Managed API · 05LoopMessage
An agent budget built around sender options
LoopMessage has configurable dedicated plans with separate phone-number, fallback and initiation options. It is a candidate when the team wants to assemble a specific sender arrangement rather than infer everything from a base price.
Dedicated Light from $59.99/month + optionsOpen review ↗Managed API · 06Photon
A choice about who operates the messaging layer
Photon documents managed tiers and a self-hosted route. Its value to an agent team is the architecture choice: pay for managed access or take responsibility for the Mac-based service.
Free / $25 Pro / $250 Business per line/monthOpen review ↗Managed API · 07messages.dev
A focused agent that answers incoming contacts
messages.dev documents a developer-oriented API, webhook verification and a contact-first production model. It is a candidate for an inbound assistant with a clear durable event-processing layer.
50 free test messages/day; confirm paid pricingOpen review ↗Managed API · 08Contiguity
An agent line budget with several published components
Contiguity’s pricing separates the number lease from iMessage access. For an agent team, the first question is which components and use-case charges belong in the production account.
$9.99 number + $69.99 iMessage/month; setup extraOpen review ↗CRM platform · 09Tuco AI
A platform with manual, assisted and autonomous modes
Tuco AI describes Manual, Copilot and Autopilot modes with a workspace and knowledge-oriented setup. It is relevant when a team wants a packaged conversation workflow rather than only a raw messaging endpoint.
Confirm monthly tier; published $335 setupOpen review ↗Own devices · 10myCRMSIM
An owned-device path for a technically prepared team
myCRMSIM describes native iPhone/eSIM use with a Mac app and an annual per-line subscription. It puts more of the messaging infrastructure in the customer’s hands.
