Go to Email → Campaigns → New drip. Add multiple messages with an interval between them (e.g. day 0, day 3, day 7, day 14). Trigger via:
- A tag on a lead or client (as soon as that tag is assigned, the sequence starts).
- A form submit via a webhook.
- Stage change in CRM (e.g. lead moved to "Qualified").
Ideal for lead nurturing: a new lead automatically receives 5 messages spread over 2 weeks, you do not have to do anything manually.
