PACE · REVIEW · LIVE CONTROL

Send on a pace you can stand behind.

Wassender gives you a final review before each run and clear controls while it sends. You choose the pace and can pause when you need to.

01 · REVIEW FIRST

Know what will happen before it starts.

Before a campaign starts, Wassender shows the recipient count, estimated duration and selected pace beside a sample of the personalized message. Take this pause to verify the audience and content.

Check the recipient total against the list you intended to use.
Read the rendered sample and look for missing spreadsheet values.
Use Back to adjust the campaign, or Start sending when the summary is correct.

02 · CHOOSE A RESPONSIBLE PACE

Set limits that fit your audience.

Pick Careful, Balanced, Fast or Custom, then review the account-safety guidance shown with your settings. Your choices affect message delays and rest breaks.

Use a slower pace for people who are less familiar with your business.
Open Safety settings to set a daily limit and optional sending hours.
Messages continue on another day when a daily limit is reached; WhatsApp Web must remain open for a scheduled run.

03 · STAY IN CONTROL

Follow the live log as messages go out.

The progress view updates as the campaign runs, with a recipient-level log that makes outcomes easy to check.

See sent, failed, skipped and remaining totals.
Pause or stop from the controls at the bottom of the extension.
Review a completed campaign in Reports for its history and recipient details.

04 · WATCH YOUR ACCOUNT HEALTH

A score that warns you before WhatsApp does.

Account health (in the dock menu) scores the last 7 days from campaigns sent in this browser: messages sent, reply rate, failures, and how many went to people who never replied. Healthy, Watch it or At risk tells you whether to slow down.

A low reply rate is the strongest warning sign — message people who know you.
Nothing leaves your computer to calculate it.

Delays, breaks and limits in everyday words

A 15–35 second delay means Wassender chooses a wait in that range between recipients. A rest break is a longer pause after a batch of messages. Neither setting guarantees that WhatsApp will not restrict an account.
With 150 recipients and a daily limit of 100, the campaign needs more than one day. Sending hours define when it may run; the daily limit defines how many messages it may attempt.
Pause holds the remaining recipients so you can continue. Stop ends the run. Messages already sent remain sent. Check the live log before deciding to resend.
An opt-out is a customer who asked not to receive campaigns. Review opt-outs in Audience and message people who expect to hear from you.

A concrete run: 3 customers, then a larger list

Import orders.xlsx and use its order-ready message. Replace the three demo phone numbers with your own test contacts. Choose Careful, inspect all three previews, then check that the confirmation says 3 people. Start only after checking the names and orders.

For a 150-person list, a daily limit of 100 allows at most 100 attempts today and leaves the remainder for a later day. If sending hours are 09:00–18:00 and you start at 19:00, the confirmation offers to wait for the next allowed time. Read that time before confirming.

Example log: Mona = sent; Omar = failed; third customer = skipped. Sent succeeded. Failed means the attempt did not succeed; read its Note before retrying. Skipped means the row was not sent, such as an invalid recipient. Pause while reviewing an unexpected result.

Phone	Name	Order	Points
12025550101	Mona	A-1042	12
+1 (202) 555-0101	Duplicate Mona	A-9999	4
—	Missing phone	A-1043	4
123	Invalid phone	A-1044	4
12025550102	Omar	A-1045	4
12025550103	—	A-1046	10

This file has 6 rows but prepares 3 recipients: Mona, Omar and the blank-name customer. The formatted Mona number is a duplicate; the blank phone is left out; 123 is too short. The first Mona row is kept, so her order stays A-1042, not A-9999.

If Omar’s number is also on your opt-out list, the prepared count drops to 2. Try this in preview; you do not need to send a campaign to inspect the count. A valid-looking phone number does not confirm that it has a WhatsApp account.

If WhatsApp restricts or bans your number

Stop every campaign and sequence, and pause Integrations sending.
Read WhatsApp's message on your phone: a temporary restriction lifts on its own after the time shown.
If the number is banned, request a review from the WhatsApp app and explain that you message your own customers.
When you start again: Careful pace, smaller lists, only people who expect your message, and more personal wording.

Wassender can't guarantee an account won't be restricted — WhatsApp decides. Reports from people who don't know you are the most common cause.
