Number Warmup Strategies to Avoid Spam Flagging

Alex Mann Alex Mann

Warm Up Your Numbers Gradually

Carriers are quick to flag new numbers that exhibit high call volumes too early

Knowing this, you can evade early spam flagging by slowly ramping up number usage. 

Consider following this warmup schedule, if time and patience allows:

WeekCalls per Day per Number
11-5
26-10
311-15
4+15-20 (if healthy)

Pro Tips:

  • Call the cellphones of other colleagues and stay on the phone over 10 minutes per call, having real conversations.
  • Start by calling warmer leads to maximize pickup rates
  • Avoid "illegitimate" calling behavior (short calls, double-dialing, no answer, low call duration)
