Pick who it goes to, see exactly what it costs and how long it takes, then send it — or schedule it, or spread it over four days so your team can keep up with the replies. Meta bills your own WhatsApp account directly; we add nothing on top.
Reach, cost per message, total cost and the number of days delivery will take — all on screen before anything goes out. A campaign to 4,820 people on a 250/day number lands over 20 days, and that fact changes whether you send at all.
WhatsApp caps how many people a number may message each day, and raises that cap as the number warms up. Tendabot reads your actual tier and paces to it, so a campaign is never throttled mid-send.
Every message can bring a reply. Spread a send over 2, 3, 4 or 7 days and a 800-person campaign becomes 200 a day — a number a small team can actually answer.
If opt-outs pass 2% the campaign pauses on its own. If Meta restricts the number mid-run it stops there too, rather than sending into a wall of failures and deepening the problem.
Meta offers no lookup, so every delivery receipt and every reply teaches the list. The audience shows who is confirmed, who is not checked yet, and who is not on WhatsApp — and the last group is skipped automatically, so you never pay to fail the same number twice.
Everyone opted in, a saved list, people active in the last 30 days, or anyone quiet for 90+ days. Include one list and exclude another — people who already bought do not need the offer again. Or pull customers straight from your Shopify or WooCommerce store: everyone who has ordered, not shipped yet, bought in the last 30 days — with the whole order history when you ask for it, and opt-outs counted and left out.
Type {name} and every recipient gets their own name. The preview renders a real contact from the audience you chose, through the same code that sends the message.
A draft never freezes its audience — the list is rebuilt when you actually send, so anyone who opted out in between is excluded and anyone who joined is included.
Sent, delivered, read and replied, live. Anything that fails is grouped by cause in plain English — "61 numbers are not on WhatsApp" rather than "61 failed".
The people the message actually reached are added to a list automatically, so the next campaign can follow up with them — or skip them.
Worth knowing before you sign up, not after.
Two parts. Meta charges per message, billed to your own WhatsApp Business Account at their published rate for the recipient's country — Tendabot adds no markup and never sits in that transaction. Tendabot itself starts at $29/month, which includes 5,000 broadcasts.
Whatever Meta allows your number, which rises as the number builds a good sending history. Tendabot reads your real limit and paces to it. You can also set a lower pace of your own if you would rather spread the replies out.
Yes. Pick a date and time and it sends on its own. A scheduled campaign still respects your daily pace, so a large list starts at that time and finishes over the following days.
The campaign pauses and tells you why, instead of continuing to send messages that will fail. Restrictions expire, and the remaining recipients stay queued for when it lifts.
Not before the first message — Meta has no lookup for that, and tools that claim one are using a personal WhatsApp Web session, which is what gets numbers banned. What Tendabot does instead: every delivery receipt and reply is remembered per contact, so before a send you see who is confirmed, who is untried, and who Meta has already refused. Refused numbers are skipped, and an untried number that fails costs nothing, because Meta only charges for delivered messages.
