You cannot unsend a WhatsApp campaign. A wrong link, a broken variable or the wrong audience reaches thousands of people instantly, and the only fix is an apologetic follow-up. Nearly all of it is preventable with five minutes of checks. Here is the list worth running every time.
Audience checks
- Is every contact genuinely opted in for this message type?
- Have you excluded your suppression and opt-out list?
- Is the segment the one you intended, and the right size?
- Have recent recipients of a similar campaign been excluded?
Message checks
- Is the template approved and in the correct category?
- Does every variable populate correctly with real data?
- Have you tested with your longest realistic values?
- Does every link work and point to the right page?
Timing and tracking checks
- Is the send time sensible for the recipients' timezone, per our timing guide?
- Are tracked links in place so you can attribute results?
- Is someone available to handle the replies this will generate?
- Have you sent a live test to yourself first?
The one check people skip
Send a real test to your own number, not just a preview. Previews do not catch broken links, awkward truncation or a variable that renders as "Hi {name}". It takes thirty seconds and catches most embarrassments.
After you send
Watch delivery and reply rates early. If failures spike, pause rather than push on, and check whether you are hitting per-user limits or list-quality problems. Keep an eye on number quality too.
Frequently asked questions
What should I check before sending a WhatsApp campaign?
Confirm opt-in and suppression exclusions, verify the segment and its size, check the template is approved in the right category, test variables with long realistic values, verify every link, pick a sensible send time, add tracked links and ensure someone can handle replies.
Why send a live test to myself first?
Previews do not catch broken links, awkward truncation or variables that fail to populate. A real test message to your own number surfaces those in thirty seconds and prevents the most common public embarrassments.
What should I do if delivery fails after sending?
Pause rather than pushing on. Check whether you are hitting per-user marketing limits, whether list quality is causing undeliverable errors, and whether your number quality rating has dropped, then fix the cause before resuming.
How do I avoid messaging the same people too often?
Exclude recent recipients of similar campaigns as part of your pre-send checks, and keep a suppression list that is always applied. Over-messaging drives opt-outs and can cause messages to be withheld entirely.
