What the public plan establishes
Textline lists API and webhooks within its business-texting offering. Its reviewed plans concern SMS and MMS, so this is an alternative workflow category. Obtain a quote for the subscription, agents, numbers and expected volume; the published pricing page does not supply one universal monthly total.
A message is not always one credit
The page explains message credits in terms of SMS segments and counts an MMS as three credits. Additional credits purchased in advance are listed at $0.03, with backup credits at $0.04. Test realistic message lengths and attachments before translating your CRM’s message count into a bill.
For the integration, request a demonstration of contact matching and reply assignment. API availability alone does not prove that a particular CRM connector maintains both correctly.
The administrator’s buying test
Inspect what the CRM stores when a message is sent, fails or receives a reply. Then make the same contact appear in two records and observe the routing. Keep the provider’s supported behavior separate from custom middleware you maintain.
Textline may be useful when the team values a business inbox and is comfortable using SMS/MMS. Ask who owns the integration, how stopped conversations propagate and which exports preserve the records you need.
