Action blocks

This article describes all action blocks that define what happens to a contact as it moves through a workflow.

Actions

  • Send Email
    Icon caret

    Sends a selected email template to contacts who have an email address and are subscribed to the email channel. The sender name and sender email can be set in the advanced settings.

  • Send SMS
    Icon caret

    Sends a selected SMS template to contacts who have a phone number and are subscribed to the SMS channel. The sender name can be set in the advanced settings.

  • Send Desktop WebPush
    Icon caret

    Delivers a web push notification to contacts who have an active desktop subscription. The TTL (time to live) can be set in the advanced settings.

  • Send Mobile WebPush
    Icon caret

    Sends a push notification to contacts with a mobile web push subscription. The TTL (time to live) can be set in the advanced settings.

  • Send Telegram
    Icon caret

    Sends a selected Telegram template to contacts subscribed to Telegram messages. The bot used for sending can be selected in the block.

  • Send Viber
    Icon caret

    Sends a selected Viber template to contacts who have a phone number and are subscribed to the Viber channel. The sender name and TTL (time to live) can be set in the advanced settings.

  • Custom send
    Icon caret

    Sends a selected template to a fixed address entered in the block, instead of the contact's own address. Available for Email, SMS, and Viber only.

  • Update Variables
    Icon caret

    Changes a variable's value, which may move the contact into or out of segments or start other workflows.

  • Number
    Icon caret

    Works with numeric variables: increases or decreases the variable's value by a specified number.

  • Subscription
    Icon caret

    Opts the contact in to or out of a selected communication channel.

  • Contacts
    Icon caret

    Manages the contact itself: activates or deactivates the contact, deletes it from the contact list selected for this workflow, or adds it to the blacklist for a selected channel (Email, SMS, or Viber). Deletion must be confirmed for safety. If the contact lacks the data for the selected blacklist, such as a phone number, it simply passes through the block.

  • Fired event
    Icon caret

    Fires a selected custom event for every contact that passes through the block. The event can then be used in other workflows, segments, or reports.

  • Duplicate to List
    Icon caret

    Copies the contact to another contact list. Variable values are copied only for variables that exist in the target list; all other variables are ignored.
