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.
Everything you need to get started
Follow these steps in WhatSender Pro to activate this feature in minutes.
-
Ribbon → Sending Mode → open Delays panel (or Campaign → Delays).
-
Set min 30 sec / max 90 sec for new numbers; 3–8 sec for warmed accounts.
-
Enable character-level typing delay, test 50 contacts, then launch full list.
Step-by-step guide
-
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.
-
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.
-
03
Enable character-level delay
Micro-pauses of 40–90ms between each character mimic real typing inside long messages — critical for text-heavy promos.
-
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.
-
05
Enable night-time pause
Optional schedule pause 11 PM–8 AM so sends follow human activity windows — reduces overnight spam flags.
-
06
Monitor countdown & adjust
Campaign status bar shows "Next message in X sec". If delivery failures rise, widen the range immediately.

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
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.
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.
