Paced like a person, because it is one

Each message goes from your own WhatsApp Web, one at a time, filled in for that person.

  • A random 30–90 seconds between messages.
  • A longer pause after every 25 to 35.
  • At most 150 a day from each number.
  • Sends only while WhatsApp Web is open.

Follow-up that keeps going

A cadence repeats on a schedule. A sequence is a short series that ends, and stops when they reply.

  • Every few days, chosen weekdays, or dates of the month.
  • Inside your send window: 9am to 6pm unless you change it.
  • Stop after a set number of unanswered messages.

Questions, answered

What is bulk WhatsApp messaging?

It's sending one message to many people at once. Syncdo does it one chat at a time from your own WhatsApp, each message filled in for that person.

Will my number get banned?

No tool can promise that. Syncdo sends one message at a time, at a person's pace, capped per number.

Is there a per-message fee?

No. Messages go from your own WhatsApp Web, so there's no API and no per-message charge.

Can I personalise each message?

Yes. Merge fields fill in each person's name and details, and spintax varies the wording.

Can I attach a PDF or image?

Yes. A template's files go with every message in the send.

How many can I send a day?

At most 150 from each number, and one send takes at most 150. The rest wait for a later send.

Can I schedule it for later?

Yes. It sends at that time if WhatsApp Web is open, and expires 24 hours after it.

Can I stop a send halfway?

Yes. Stop a batch partway and retry the ones that failed; Campaigns cancels anything still queued.

Does it send at night?

Cadences and sequences send only inside your send window, 9am to 6pm unless you change it.

Which plan do I need?

Essentials or Intelligence. Bulk send is on both paid plans.

The right message, to every right customer.
