Agent builder adds four messaging providers and still can’t reach users reliably
iamstanty · reddit · 2026-07-28
A developer built an agent that lives in group chats and found that user reach is still unreliable even after stacking multiple messaging providers.
- Started with Sendblue for iMessage, but ran into its free-plan verification rule.
- Paid to remove the restriction for groups, then added Telegram and SMS as fallbacks.
- Added Linq as a fourth provider because it covers iMessage, RCS, and SMS through one API.
- The underlying question: is provider stacking the only way to make agent messaging reliable, or is there a better single-channel setup?
