One message, a hundred thousand people, every reply in the inbox

Up to 100,000 recipients per campaign, each counted once. A saved segment can hold 200,000 members, and a campaign sent to it takes a snapshot of the members at the moment it starts preparing, so later changes to the segment do not affect a scheduled send.

On the official WhatsApp Business Platform, messaging outside the 24-hour customer-service window requires a pre-approved template, and review usually takes 24 to 48 hours. Lodgestory enforces this before scheduling: a campaign against a template that is not yet approved will not save, so a broadcast can never queue against a pending template. Unofficial numbers have no templates and no window, and send free text at a much lower rate.

Template campaigns fill every slot from a campaign-wide value, a standard or custom contact field, or a column of the CSV or segment, with an optional fallback for recipients who have no value. Free-text and email campaigns use named tokens such as {{firstName}} or {{offer_code}} in the body and the subject. Segment attributes work as CSV columns.

Around 600 messages a minute on WhatsApp Official and around 6 a minute by default on unofficial numbers and email, released in a controlled stream rather than all at once. Three settings govern the pace: how many sends run at the same time, how often a new send starts, and how many a number may send per minute. The slowest of the three always wins, and several campaigns running at once share the same capacity.

Every recipient has their own status. A transient refusal retries automatically with back-off, up to the limit you set between one and ten attempts. A permanent failure, such as an invalid number or an opt-out, stops trying and logs the reason. You can cancel a running campaign at any time; messages already sent cannot be recalled, but nothing further goes out. The failed or not-delivered stage of any campaign can be picked as the audience of the next one.
