GuidesTexts in automations

Texts in automations

An automation can text a contact as one of its steps, beside its emails. The step is send_sms, and it lives on the same canvas.

The step

{
  "id": "text_reminder",
  "type": "send_sms",
  "config": {
    "text": "Your cart is waiting. Finish your order: acme.co/s/cart",
    "category": "marketing"
  }
}
  • text is required unless media_urls has an image. Contact properties can be merged in, as in an email.
  • category is marketing unless you set transactional, for a text the person needs because of something they did.
  • from is optional; your default number for the contact's country is used.

When a contact cannot get the text

A contact without a phone, without SMS consent for a marketing text, or who texted STOP skips the step, and the run carries on with the next one. The run's history says which step was skipped and why.

A marketing text that falls outside 8 am to 9 pm in the contact's time zone waits for the morning, and the run waits with it.
