Syncdo broadcasts to a filtered list of your own contacts — each person gets the message by name, from your own WhatsApp, one at a time. Not a spam blast. Not a list everyone mutes. Just the right message, to the right people, personally.
Something changes — new stock, a price, a reminder, an offer — and everyone needs to know. So you open chats one by one, paste the same message, retype each name. An hour gone. Or you skip it, and the sale goes to whoever else reached them first. Or you fire off a broadcast list where every message reads identical and impersonal — and most of them get muted.
Copy-paste all evening, or blast and get ignored. Those shouldn't be the only two options.
Filter your contacts down to the people who should get this — by what they buy, where they are, or where they sit in your pipeline. Write your message once, with their name and details built in. Syncdo sends each person their own message, from your own WhatsApp, one at a time and naturally paced. A hundred people hear from you, and every one feels like the only one.

This isn't a blast tool and it isn't a bot. Every message goes to your own customers — people who already talk to you — one at a time, from your own account, personal and naturally paced. That's not just safer, it's why your messages get read instead of muted. Businesses whose broadcasts get ignored sent a list a message. You're sending people a message.
One personalized send reaches everyone once. What usually decides the outcome is what happens next — the second message to the people who never replied, and the third a week later.
A cadence is that follow-up written down: a series of steps, spaced over days, that keeps working a lead until they answer or you stop it. A sequence is the same idea applied to a whole segment. Both send through your own WhatsApp under the same ceilings and the same sending hours as a one-off send — the pacing rules do not loosen because the message was scheduled.
Personalized sends, cadences and sequences are all on Essentials and up. The free plan has the CRM — leads, stages, notes, history — without the sending tools.
Compose the whole thing now — the filter, the template, the people it will reach — and pick a time instead of pressing send. Syncdo queues it against your number and starts working through it then, at the same pace and under the same ceilings as a send you started by hand.
It sends from your own WhatsApp, so WhatsApp Web has to be open at that time. Nothing goes out from a server while your laptop is shut — that is the point of the product rather than a limitation to engineer around, because the messages come from your number and your session.
And if the moment passes, the messages are missed rather than sent late. Every queued message carries an expiry, so a laptop closed for three days does not open on a burst of messages whose moment has gone — a Tuesday price update should not land on Friday. You can also cancel a campaign before it runs: anything still queued stops, and anything already sent stays sent.
Yes. You're messaging your own customers, one at a time, from your own account — the same way you would by hand. Syncdo just saves you the hour. No unofficial APIs, no bots.
Bans come from spamming strangers with identical messages at speed. This is the opposite: your own people, personal messages, natural pacing. Message people who expect to hear from you and you're using WhatsApp exactly as intended.
A broadcast list sends everyone the same text and only reaches people who've saved your number. Syncdo personalizes every message and lets you send to exactly the right segment — by product, city, stage, or any detail you keep.
Yes. Their name, their company, any detail you track — filled in per person. If something's missing, it's simply left out, so nothing ever looks broken.
Yes. Compose it now — the filter, the template, the recipients — and pick a time instead of pressing send. Syncdo queues it against your number and starts working through it then, at the same pace and under the same ceilings. You can cancel it any time before it runs.
No. Messages go out through your own WhatsApp Web session, so it has to be open at the time. Nothing is sent from a server on your behalf.

Essentials or Intelligence. Personalized sends, cadences and sequences are all on the paid plans; the free plan has the CRM — leads, stages, notes and history — without the sending tools.
Yes — that's a cadence: a series of steps spaced over days that keeps working a lead until they answer or you stop it. A sequence applies the same idea to a whole segment. Both run under the same sending hours and the same ceilings as a one-off send.
Inside the sending hours you set — 9am to 6pm by default. Anything queued outside them waits, so a message you set up late at night reaches people the next morning instead of at 2am.
Anyone in your contacts — filter to a segment and send only to them. Sending is paced to protect your number rather than to be used up: messages go out 30–90 seconds apart, in bursts of 25–35 with a 25–35 minute pause between them, up to 150 from a number in a day. A larger list keeps going at that pace instead of going out faster.
Reach exactly the right customers — personally — without ever leaving WhatsApp.
