Should you ask for a phone number when people subscribe to a newsletter?

More people hand over a phone number than you'd expect. On my local brands the share giving one has ranged from about 20% of survey completers up to around 40% of signups, and one newer funnel hit 38% phone capture, double my earlier rate.

The harder question is what you're allowed to do with those numbers.

How many subscribers give a phone number?

Setup	Phone numbers
Optional phone field, early 2026	About 20% of survey completers, roughly 10% of all subscribers
One list of about 13,000 subscribers	About 1,800 numbers
A regular local newsletter with a post-signup survey	About 30% to 35%
A later version of my survey	About 40%
A funnel with a conditional lead card (2026)	38% phone capture

My guess is seniors would give their numbers at an even higher rate. I haven't proven that yet.

Does asking for a phone number hurt signups?

The conventional advice says yes. I heard a finance newsletter operator at a conference say he A/B tested it hard and found zero difference, so all his forms now ask. That's his audience, and finance subscribers are more guarded than most. I'd argue local readers are probably less guarded, not more.

I'll be honest about my own data: I hadn't checked my cost per subscriber since adding the field when I said that. Keep the phone field optional and inside the post-signup survey, never on the first email-only step.

For a writer-recruitment ad aimed at younger people, I dropped the phone field from the lead form entirely, to cut friction.

Why did I stop collecting phone numbers?

"I was getting about 40% of people's phone numbers. But with the legality of TCPA laws I realized I can't do anything with those phone numbers for now. Cause you'll get sued."

A peer walked me through what compliance actually requires, and my takeaway was that showing disclosure text on a page isn't enough. You need stored proof of consent for every person:

• The IP address they submitted from
• A timestamp
• The exact form data they submitted, including the consent language they saw

My form didn't track that, so I removed the phone field and had my AI builder start adding the tracking. I'm not a lawyer, and this isn't legal advice. Talk to one before you text anybody.

Is SMS worth it for a local newsletter?

I'm not convinced. A lot of people in the newsletter space are talking about SMS, but every text costs money, and I don't know how much sense that makes in local yet.

Phone numbers are more interesting as a lead asset. If a subscriber says they're buying a home or shopping for insurance, a phone number makes that lead far more valuable to a local partner. That's where I see the upside, once consent, legal review and the capacity to actually call people are handled.

What should you do Monday?

1. If you collect numbers today, check whether you can prove consent for each one.
2. If you can't, stop collecting until you can, or talk to a lawyer.
3. If you can, keep the field optional and put it late in the survey.
