| Option | How a run begins | Good at | Keep in mind |
|---|---|---|---|
| Letaido AI agent | A set time, such as every hour or every morning, a mention of @Letaido in Slack, or a request in chat | Grouping the hour's texts with opt-outs first, posting calls nobody picked up, a daily SMS delivery report with error codes, and answering questions about one number in a thread | Twilio has no event trigger in Letaido, so texts and calls are posted on a schedule, not the moment they arrive. Replies typed in Slack are not sent back as texts. The missed call check runs 15 minutes past each hour and skips calls still ringing then; they are not checked again |
| Twilio's SMS-to-Slack Studio tutorial | A text arriving at your Twilio number | Posting each incoming text to one Slack channel as it arrives, using a Studio Flow and a Slack incoming webhook | You build the Flow, create the Slack webhook and write the message payload yourself. As written, the tutorial posts each text as its own Slack message, with no grouping or summary |
| Zapier, n8n and other recipe tools | A new Twilio text, a finished Twilio call or a new Slack message starts a recipe | Forwarding Twilio texts to a Slack channel or DM, posting new Twilio calls, and sending a text when a Slack message is posted. Other Twilio data needs raw API calls (Zapier's API Request action, n8n's HTTP Request node) | Zapier checks for new Twilio texts every 15 minutes on its lowest plan. A simple forwarding recipe posts each text or call as it comes; filtering missed calls, looking up one number or summing up a day needs API calls plus extra filter and count steps you build |

Frequently asked
Can Twilio send texts to Slack? +
Yes. Twilio's SMS-to-Slack tutorial posts each incoming text to Slack through a Studio Flow and a Slack webhook you set up. With Letaido, Leta posts the texts sent to your Twilio number every hour, with opt-outs like STOP grouped at the top, and a daily SMS delivery report with error codes.
How do I connect Twilio and Slack to Letaido? +
Paste a Twilio API key into Letaido and create the Slack app from Letaido's manifest. Invite the Letaido bot to the channels it should post in, then describe the job in chat, or paste a prompt from a job on this page.
Is a new Twilio text posted to Slack right away? +
No. Twilio has no event trigger in Letaido, so texts are posted every hour and missed calls every hour at 15 past. Each run covers the previous full clock hour, so back-to-back scheduled runs never overlap. The missed call job only judges calls already finished at its check: a call still ringing or in progress then is skipped and not checked again. An hour with nothing new posts nothing.
What happens when I mention @Letaido in Slack with a phone number? +
Leta replies in the thread with the texts with that number created in the past 7 days, including any that failed before sending, with their status and what any error code means.
Can Slack send SMS messages? +
Not through these jobs. Replies typed in Slack are not sent back as texts. Reply from your usual texting tool, or ask Leta in chat to send a text.
Will these jobs text my customers? +
No. Twilio is only read in these jobs, so they send no texts and place no calls. The only write is the Slack post.
Does Zapier connect Twilio to Slack? +
Yes. A simple Zapier forwarding recipe posts each Twilio text or call to Slack as it comes, and Zapier checks for new Twilio texts every 15 minutes on its lowest plan. Lookups and daily reports there need Twilio API calls plus extra filter and count steps. Leta groups the hour's texts, works out which calls nobody picked up, sums up a day of delivery results and answers questions about one number in a thread.
