Sending and automation
Create an advanced campaign and validate numbers
Save a campaign draft using a reusable sequence or several messages.
Before you begin
Use Comfort for the detailed form. Have an active trial or subscription for sending, a connected device and intended recipients. A sequence is an ordered set of messages; upload attachments to Media first.
What to do
- Open Campaigns in Comfort and choose Advanced mode.
- Enter a name for the campaign.
- Select the sending devices.
- Choose Use saved list or Type numbers, then provide the recipients. Check the count against the 10,000-contact limit.
- Choose Use saved sequence and select one, or Create now to write the messages. The detailed editor accepts up to 10 messages.
- Set each message’s content and, when supported, its media caption.
- Set Delay in seconds for each message’s wait.
- Set Interval between contacts and Variance in seconds for pacing between recipients.
- Choose Create Campaign. It appears as a Draft and has not started sending.
- Choose Validate on the draft when you need to check whether numbers are registered on WhatsApp. Wait for the results before starting.
- Choose Start after reviewing the draft and validation results.
Worked example
Fictional example: create Workshop follow-up from a saved list and a two-step sequence: Thanks for attending, then Your notes are ready. Use a 3-second message delay and a 10-second contact interval. Save the draft, inspect it and validate before choosing Start.
How to check it worked
The draft appears before sending. Validation reports its checked count and any invalid numbers. After Start, the campaign status and report show execution progress.
What to know
- Validation places numbers reported as unavailable into the saved list Inválidos and removes those numbers from the campaign. It does not establish permission to send.
- Stop validation interrupts checking. A connection error can leave a number unconfirmed rather than classify it as invalid, so a clean result is not proof every check succeeded.
Common problems

- The saved sequence is missing or empty.
- What to do
- Open Sequences and save at least one usable message, then reopen the campaign form.
- What to expect
- The saved sequence is available for selection.

- What to do

Keep the browser tab open during sending. Use Pause before investigating stalled progress, and Resume only after checking the existing report.
