The short version. Bring your actual workflow to the evaluation. A provider should be able to explain how a first message becomes a useful conversation your team can manage.
1. Who starts the conversation?
Write down whether customers normally message first or your business initiates an expected follow-up. Inbound-first plans and outbound-capable plans can have different prices, limits, and onboarding. Sendblue’s current pricing is an example: its $100 AI Agent plan and custom Enterprise outbound plan are listed separately.
2. What does “unlimited” leave out?
Ask about message pace, new contacts per day, number of lines, attachments, and acceptable use. Miss Blue’s homepage describes unlimited continuing conversations alongside limits for new contacts and sending pace. A monthly billing label does not erase those operating boundaries.
3. Can your whole team work the reply?
An inbox should make the next action clear. Check the history a teammate can see, who is responsible for replying, and what happens when an automation and a person both try to act. Test the handoff with two teammates, not just the person evaluating the tool.
4. What does the CRM connection actually do?
Separate a native integration, an automation recipe, and a custom API project. Ask which records sync, where replies appear, and how failed events are recovered. Include setup and maintenance in the budget when a connection requires work. A provider’s guide is useful evidence of an approach, not proof that your particular setup is complete.
5. What happens outside iMessage?
Check fallback to RCS or SMS using a recipient who cannot receive iMessage. Confirm the number the recipient sees, reply handling, media behavior, and which delivery signals the fallback channel supplies. Both Miss Blue and Sendblue describe fallback, but the specific user experience still deserves a test.
6. Who controls the number and the exit?
Ask how a number is provisioned, what a transfer requires, how long it normally takes, and what happens if you leave. Check exports for contacts and conversation records. An inexpensive entry plan can become inconvenient if the operational exit was never discussed.
7. What is the full monthly commitment?
Calculate lines, seats, calling, setup, message-related charges where applicable, and integration services. Label introductory prices and the conditions that keep them active. Ask for a written quote when a plan is custom. The comparison on this site includes a base-line calculator, with its exclusions stated beside the result.
Finish the evaluation with a short list of observed results and unresolved questions. Buy when those answers support your workflow—not because a review gives a product an unexplained score.
