#What is Total Contacts?

This is the total number of contacts this number actively messages.

• Recommended cap per number: up to ~3,000 active contacts
• Above this, you should start spreading traffic across more numbers

#Why it matters

While there’s no single magic limit, trying to run an entire operation from one phone number concentrates all risk in one place.

#How to improve this metric

• Add additional numbers as your audience grows beyond a few thousand contacts
• Segment by product line, geography, or funnel so each number owns a slice of traffic
• Move inactive or low-value contacts to lower-priority numbers or channels

#Best practices

• Think in terms of “numbers per X contacts” instead of “one number for everything”
• Use this metric together with Daily Messages and Burst Rate to make sure each number stays inside safe capacity.
