Cadence

Cadence is the timing pattern between sent messages — intervals, batches, times. Human cadence mimics the natural rhythm of conversation. Robotic cadence is detected by WhatsApp and leads to blocking.

Why cadence matters

The WhatsApp anti-spam algorithm notes: sending 50 messages in the same second is humanly impossible, therefore, it is a bot. Random cadence between 5-30 seconds imitates real typing, batch of 10-20 messages imitates "responding to several at once", pause of 10-30 minutes between batches imitates "went to the bathroom".

Cadence by number age

Number age	Interval between sends	Lot	Pause between batches
0-7 days	Do not send	—	—
7-30 days	30-60s random	5-10	20-40 min
30-90 days	20-45s random	10-20	15-30 min
90+ days	15-30s random	15-30	10-20 min

Signs of wrong cadence

• Frequent "undelivered" messages.
• WhatsApp Web status disconnecting alone.
• Temporary blocking (24h) — first warning of excess.
• Permanent ban — last season.

Text variation

Along with the temporal cadence, vary the text: "Hello, how are you?" alternates with "Hi, how are you?" Zapext allows you to define 3-5 variations per message; the system chooses randomly for each submission.
