The Wait Until block holds a person in your workflow until they meet a condition. Unlike a time-based delay, progression depends entirely on whether the condition becomes true.

How it works

When a person reaches a Wait Until block:
  • If they already meet the condition, they skip the wait and move on immediately.
  • If they don’t yet meet the condition, they remain paused until they do.
There’s no maximum fallback — people stay in the wait until the condition is met.

​
Conditions

Wait Until supports three types of conditions: Variables
Match profile data stored as variables. For example:
  • plan_type = enterprise
  • trial_active = false
Engagement
Match actions a person has or hasn’t taken with your emails, such as:
  • Was sent a message
  • Opened or clicked a message
  • Did not engage with a specific campaign
Audience
Match whether someone is in or not in an audience segment. For example:
  • In “Active Customers” audience
  • Not in “Churned” audience

​
Key behaviors

  • Immediate skip: If someone already matches the condition when they enter, they move on without waiting.
  • Indefinite wait: If they don’t, they’ll pause until they qualify.
  • Multiple conditions: You can add multiple groups of conditions joined by AND (must all be true) or separate paths joined by OR (progress as soon as one path is true).

​
Best practices

  • Use for conditions that must be satisfied before continuing, like “Wait until trial ends” or “Wait until in Active Customers audience.”
  • Be cautious when using only negative conditions (like “not in audience”), since people may wait indefinitely.
  • When mixing with time-based delays, place Wait Until either before or after the delay depending on whether you want time or conditions to take priority.
