How to Keep Your Caller Reputation Strong

People value getting phone calls that are relevant, safe, and not annoying. We want your legit business calls to get through - without being blocked, labeled as spam, or ignored. Here are practical tips to help you maintain a good caller reputation and improve answer rates.


Why Caller Reputation Matters

  • Regulators and carriers are stepping up efforts to reduce unwanted and spammy calls.

  • If your calls look “spammy” (even if they aren't), they might get blocked or filtered.

  • A strong caller reputation increases the chances people will pick up and trust your calls.


Best Practices: What to Do & Avoid

Here are the basic “Do’s” and “Don’ts” to help protect your reputation.

✅ Do

🚫 Don’t

Follow laws and lists - Comply with the U.S. “Do Not Call” registry and rules like the TCPA.

(e.g. https://www.donotcall.gov/ US Only), and other Telephone Consumer Protection Act (TCPA) Act 47 U.S.C. § 227 requirements (US Only).

Ignore “Do Not Call” lists or regulations.

Clean up your call list - Remove numbers that never connect; keep your contact list fresh.

Keep calling numbers that are invalid, disconnected, or that always reject your calls.

Provide clear contact info - Let people know who’s calling and how to report problems.

Use hidden or confusing caller ID or leave no way for people to reach you back.


Keep Number Usage Consistent

This means using each phone number for the same kind of thing consistently.

  • Avoid using one number for wildly different uses (e.g. marketing + surveys + support).

  • If a number was used before and then changed to something else, let it “rest” for about 45 days before using it for a new campaign. This gives carriers time to adjust.


Manage Your Call Volume Carefully

How many calls you make, and how often, can impact whether your calls are seen as spam.

  • Start small when launching a new campaign and gradually increase call volume.

  • Don’t suddenly jump from zero to tons of outbound calls.

  • Avoid calling too frequently, especially to the same person. For example, calling someone 8 times in 7 days might be considered harassment under certain U.S. laws (like the Fair Debt Collection Practices Act).


Mind the Timing and Respect Preferences

  • Call only during reasonable hours. (General business hours usually make sense.)

  • Let people tell you how often they want to be contacted, and by which method.

  • If someone asks you to stop calling via a certain number or channel, honor that preference.


Frequently Asked Questions

What if my calls are labeled “Spam” or “Spam Likely”?
Following the practices above, and registering with tools like SHAKEN/STIR (a system many carriers use to validate caller identity) can help reverse or reduce these labels.

Are these rules mandatory?
Not all of them. But the more you follow them, the better your chances of avoiding issues like being blocked or having low pickup rates.
