Anti-Block Delays human-speed pacing

Anti-Block Delays simulate real human typing — variable pauses between characters and messages so bulk sends look like manual outreach. This is the single most important setting for avoiding WhatsApp restrictions on unofficial accounts. Wider min/max ranges and character-level micro-delays dramatically reduce ban risk.

Quick start

Follow these steps in WhatSender Pro to activate this feature in minutes.

  1. Ribbon → Sending Mode → open Delays panel (or Campaign → Delays).

  2. Set min 30 sec / max 90 sec for new numbers; 3–8 sec for warmed accounts.

  3. Enable character-level typing delay, test 50 contacts, then launch full list.

How it works

Step-by-step guide

  1. 01
    Open Sending Mode delays

    Click Sending Mode in the ribbon or go to Campaign → Delays. The delay panel shows min/max sliders and character typing toggle.

  2. 02
    Set message gap range

    Example: min 3 sec, max 8 sec — WhatSender picks a random value between them for each send. Never use a fixed single number.

  3. 03
    Enable character-level delay

    Micro-pauses of 40–90ms between each character mimic real typing inside long messages — critical for text-heavy promos.

  4. 04
    Choose a preset for account age

    New number: 60–120 sec. Warmed (2 weeks): 30–60 sec. Mature: 4–10 sec. Media campaigns: add 50% to all values.

  5. 05
    Enable night-time pause

    Optional schedule pause 11 PM–8 AM so sends follow human activity windows — reduces overnight spam flags.

  6. 06
    Monitor countdown & adjust

    Campaign status bar shows "Next message in X sec". If delivery failures rise, widen the range immediately.

Comparison

Delay settings impact

0 sec delay (danger)

  • 500 messages in 2 minutes
  • Obvious bot traffic pattern
  • High restriction risk within hours
  • Typical on free bulk tools

3–8 sec randomized (safe)

  • Human-paced send rhythm
  • Character typing simulation
  • Sustainable 500–1,000/day
  • Pairs with Anti-Block v4 matrix
Business impact

How this helps your business

  • #1 ban prevention tool

    Instant zero-delay blasts are the top trigger for WhatsApp restrictions — delays fix that.

  • Carrier-safe traffic patterns

    Randomized gaps make your sends indistinguishable from manual typing.

  • Per-team configuration

    Conservative delays for new numbers; faster pacing for warmed agency accounts.

  • Stacks with rotation & v4

    Delays + multi-account rotation + Anti-Block v4 = sustainable 5,000+/day.

  • Media-aware pacing

    Automatic longer gaps when sending images, PDFs, or video attachments.

Pro tips

Best practices

  • Never set 0 delay on promotional blasts — even on mature accounts.
  • Use 8–15 sec minimum for media-heavy campaigns.
  • Randomize min/max — a fixed 5-second gap looks robotic to detection systems.
  • Pair with Safe Mode (not Blind Mode) for cold contact lists.
  • If you see "account may be restricted", immediately increase delays to 90–120 sec.
