Reactivation Email vs Text: What Gets Replies

The first question about reactivation email versus text is not which one performs better. It is what these people agreed to receive. The rules are asymmetric: commercial email to existing contacts is lawful with accurate headers and a working opt-out, while commercial texts require written consent, which most old databases simply do not have on file. That single fact decides the channel for half your list before performance enters the conversation.

Where both channels are available, they do different jobs. Text is the attention channel - read within minutes - and email is the substance channel, carrying context, links and the reply that a careful message earns. This comparison covers the rules, the evidence, the costs, and a segment-by-segment framework for choosing.

Key takeaways

• Consent is asymmetric. CAN-SPAM allows commercial email to existing contacts with accurate headers and a working opt-out; commercial texts require written consent under FCC rules, and revocation must be honored promptly.
• Attention favors text. Textmagic's 2025 survey of 1,800 U.S. consumers found only 8% say they ignore business texts outright, but nearly 70% have blocked a business number, with 48% of those citing excessive frequency or irrelevance. Text is powerful and easy to lose.
• Content favors email. Length, formatting and links live there; SMS rewards one question in roughly 160 characters, and Project Broadcast's analysis of more than 170 million texts found message length itself affects reply behavior.
• Project Broadcast's data also shows conversational messages consistently outperform broadcast blasts, with some message types producing up to 17 times the reply rate of others.
• Mailchimp's benchmark data (average open rate 35.63%, click rate 2.62%) comes with an explicit warning that Apple's privacy changes make opens unreliable - so do not steer a reactivation campaign by open rates.
• Email sends cost almost nothing at campaign scale, Twilio lists U.S. SMS at $0.0083 per outbound segment plus carrier fees, and both are dwarfed by the labor to answer replies.

The decision that is not about performance

Start with what each channel is allowed to do for each contact.

• Email. CAN-SPAM covers commercial messages, including email to former customers. Requirements are real - accurate headers, a clear opt-out, a working unsubscribe, and honoring opt-outs within 10 business days - but prior written consent is not the bar.
• Text. FCC rules require prior written consent for commercial texts, and the number must have been collected with the disclosure the person actually saw. Revocation must be honored promptly, and even people who never opted out can stop you at any time in any reasonable manner.
• Phone. Telemarketing calls respect the National Do Not Call Registry and the 8am to 9pm local quiet-hours window, which the FCC also applies to texts.

If you cannot produce the consent record for a contact, the text option does not exist for them. No performance number outranks that. Our SMS compliance guide covers consent language, registration and record-keeping in detail.

How the channels actually behave

What the data says, and what it cannot tell you

Three datasets are worth citing, with their limitations attached.

Textmagic's 2025 survey of 1,800 U.S. consumers found only 8% say they ignore business texts, the lowest ignore rate of any channel it measured. It also found that nearly 70% of respondents have blocked a business number, 48% of those multiple times, citing excessive frequency or irrelevance. Among ignored texts, 41% were ignored for irrelevance and 39% because the sender seemed questionable. The lesson is not that SMS wins; it is that SMS is a borrowed privilege you lose by being irrelevant or unrecognizable.

Project Broadcast's PB Data Labs report, built from more than 170 million texts sent in 2025, found conversational messages consistently outperform broadcast blasts, that message length affects reply behavior, and that some message types generate up to 17 times the reply rate of others. The limitations: it is one platform's data and its raw numbers are not public in the summary. The direction - conversations beat campaigns - matches every other dataset here.

Mailchimp's email benchmarks put the average open rate at 35.63% and the average click rate at 2.62% across users, with an average unsubscribe rate of 0.22%. The page carries its own warning that Apple's Mail Privacy Protection makes open rates unreliable, which is why experienced operators track clicks and replies instead. The data was last refreshed in December 2023, so treat it as a shape, not a precise reading.

None of these numbers predict your campaign. Survey respondents and platform averages describe populations, not your list, your offer or your reputation with the people in it. The HBR finding that acquisition costs five to 25 times retention explains why the campaign is worth running carefully rather than why any particular channel will work.

A segment-by-segment framework

The tone rules for every one of these segments are in our reactivation playbook, and the word-for-word examples are in the reactivation text examples library.

The same message, written for each channel

Every reactivation message has one job: give a true reason and make saying no easy. The channels change the packaging, not the job.

Email version:

Subject: Your last service was in March - want the fall slot?

Hi Maria - you had us out for a tune-up in March, and that puts you right at the interval where we would normally take another look. We have openings the week of October 6. Want me to hold one? If it is not relevant anymore, just reply and I will close the file.

Text version, to someone with documented consent:

Hi Maria, it is Dana at Northside. Your March tune-up is due again - we have a fall slot open next week. Want it? Reply YES or no worries at all.

Notice what the text version gives up: the subject line, the explanation, the calendar precision. What it keeps: identity, the reason, and the exit. That trade is the entire comparison in miniature.

The hybrid sequence most teams should run

1. Day 0: email opener to the whole segment. Lawful for existing contacts, and it filters for the people who actually read.
2. Day 2 to 3: text follow-up to the consented subset only - short, one question, no link required.
3. Day 14 to 21: email close-the-loop that tells non-responders you are stopping and leaves one door open.
4. Throughout: call the replies and the high-value non-responders. A real conversation closes what the message opened.

The email nurture workflow and the SMS nurture workflow are the built versions of the first three steps, and the database reactivation workflow adds the segmentation and stop rules. An AI reactivation agent runs the same sequence with reply handling attached, which matters because a wave of replies with nobody answering is worse than no campaign at all.

How to test the channels fairly

• Split one segment, not two. Both arms need the same relationship, same offer, same timing window. Comparing email results from warm customers to text results from cold ones tells you nothing.
• Sample size before conclusions. A few hundred contacts per arm, minimum. Low hundreds will mislead you with noise.
• Score replies per 100 contacts first, then bookings per 100, then opt-outs and complaints. Opens are not a metric for either channel here.
• Run the test once, then decide. If the text arm produces replies and zero complaints, expand it. If opt-outs spike, the segment was too cold or the copy too salesy - fix the input, not the channel.
• Never text a contact who has not consented, even in a test. There is no experiment worth a spam complaint.

Next step

Pick one consented segment and run the hybrid sequence at a size you can genuinely handle - fifty contacts is a fine first wave. If you want the channel logic, consent gates and stop rules built into a system rather than maintained in a spreadsheet, map it through the six-step intake or book a call and bring your segment counts.

FAQ

Should I email or text old contacts first?

Email first when consent history is thin, because CAN-SPAM allows commercial email to existing contacts with accurate headers and a working opt-out. Text only the segments where you have documented consent that covers marketing messages. Call the high-value dormant contacts when the list is small enough to work by phone.

Which channel gets more replies, email or text?

They are not interchangeable, so a single winner is the wrong frame. Textmagic's 2025 survey found only 8% of consumers say they ignore business texts, which makes SMS the attention channel, while email carries the length, links and planning detail that reactivation often needs. Test within one consented segment before trusting anyone's ratio, including ours.

Can I text old leads who never opted in to texts?

No. FCC rules require written consent for commercial texts, and a number collected for a callback or a quote is not permission to send marketing. If you cannot show the consent record, that contact does not get a text; use email or the phone.

Do I need to register my number before sending reactivation texts?

Yes, if you send application-to-person texts from a standard 10-digit U.S. number. Carriers require A2P 10DLC brand and campaign registration, and unregistered traffic gets filtered and charged extra fees. A message that never arrives cannot get a reply.

What about calling old contacts instead?

Calls are the highest-signal channel for the quoted-but-never-closed and high-ticket segments, and the FCC quiet-hours rule applies: nothing before 8am or after 9pm local time. Use calls where the deal size justifies the minutes, and keep texts for consented, time-sensitive, short messages.
