How Can I send a second email 5 days after the first one was sent? The real problem is that we need make it dynamic, we do not have a date, we create a lead, and send an email, but 10 days after I need send a second email. But I don't have an specific date
If you want to send to your same audience as the first, in your flow, add a wait step 5 days and another email flow step with your other email.
Per the above the email will send 5 days post entering the wait step. If you'd like to change the send time, you can use the flow step to control this further. Search for documentation on wait steps for this.
