    Does database reactivation work? The short answer

    Yes, it can. Database reactivation books jobs from people who already know you, but the published numbers vary a lot and most of them come from companies selling it.

    Database reactivation means reaching back out to old leads, unsold estimates and past customers already in your list, finding who still needs the work, and helping them book.

    Here's the honest version:

    • There is no neutral industry benchmark. Most published numbers come from companies that sell reactivation.
    • Published HVAC and plumbing cases land in the low single digits as a share of the list that books.
    • Dental cases run higher, because a checkup is easy to say yes to.
    • List age, consent and how fast someone answers the replies decide more than the message does.

    Let's go through the numbers.

    What the published numbers say

    Read these as examples, not averages. Companies publish the campaigns that went well.

    HVAC and plumbing

    • One marketing agency's published case write-up reported that a contractor sent to 5,000 database contacts and got 300 replies, 119 booked appointments and 29 completed jobs. Results vary by business and list.

    Look at that closely. 119 bookings became 29 jobs. What that means is "booked" and "paid" are not the same number. Ask which one anyone is quoting.

    Dental

    • One marketing agency's published case write-up reported that a UK practice texted 800 lapsed contacts. 94 replied within 72 hours and 61 booked. Results vary by practice and list.
    • One marketing agency's published write-up reported that a single postcard or a single email usually gets 1% to 3%, while a sequence across text, email, phone and mail typically books 8% to 15% of contacted patients within 60 days. Results vary by practice and list.

    What decides your results

    1. How old the list is

    Newer contacts answer more. One marketing agency's published write-up reported that contacts up to 24 months dormant reliably produce bookings, and contacts past 36 months rarely justify the opt-outs they cost. So start with the most recent people and work back.

    2. How much of the list you can actually reach

    Old lists are messy. The same write-up reported that a med spa export that looks unusable typically has 60% to 75% reachable after duplicates and opt-outs are removed. Another marketing agency's published write-up reported that 15% to 25% of contact records are outdated for patients inactive longer than two years. Your results should be measured against the people you can reach, not the size of the export.

    3. How fast someone answers the replies

    A reply is a person raising their hand. If it sits until tomorrow, they book someone else. For example, a homeowner in North York replies "yes, my furnace is making noise" at 6 pm. The company that calls back tonight gets the job. That's why we put a dedicated SDR on every reply.

    4. One channel or several

    The dental numbers above show the gap between one postcard and a full sequence. More channels also means more consent to check.

    5. Consent comes first

    Check consent before you message anyone. The rules differ by country, and the details of your list matter.

    • US. Under the TCPA rules, marketing texts sent with an autodialer, and marketing calls that use a prerecorded or artificial voice, need the person's prior express written consent (47 CFR 64.1200(a)(2)). The FCC treats an AI-generated voice as artificial (FCC 24-17). A past purchase can help with the Do Not Call Registry rules, but it does not replace written consent. New opt-out rules take effect November 25, 2026 (FCC 26-67), and many states add rules of their own.
    • Canada. CASL covers texts and emails. You have implied consent for 2 years after a purchase, while a written contract with the person is active and for 2 years after it ends, and for 6 months after an inquiry or application (CASL s.10(10)). Outside those windows, you need express consent. Every marketing text or email also needs your business name, your contact information and a way to unsubscribe (CASL s.6). Phone calls follow separate telemarketing rules with different time windows.

    Both are covered in our guides: US texting laws and texting past customers under CASL. Some of your list may only be reachable another way, and some people you may not be able to message at all. Your lawyer can tell you which.

    What reactivation won't do

    • It won't fix a list of people who never contacted you. Bought lists are not reactivation.
    • It won't keep working at the same rate every month. The first send to a list usually does the most.
    • It won't guarantee bookings. Results depend on your list, your consent records, your offer and how fast replies get answered.

    How to test it on your own list

    1. Export your past customers, old leads and unsold estimates with the last contact date.
    2. Remove anyone who opted out, and anyone you don't have consent to message.
    3. Start with the last 12 to 24 months.
    4. Write one plain message that sounds like your office, with your business name, how to reach you, and a way to opt out.
    5. Have someone ready to answer every reply the same day.
    6. Track four numbers: replies, booked, showed, paid.

    What makes the difference

    Most agencies automate the follow-up, or hand it back to your front desk. A text goes out and a link gets sent, but often nobody calls. In a Growth Partnership, a dedicated SDR follows up with every lead by call and text and books the ones who are ready. Results not guaranteed.

    How this fits into your growth plan

    Reactivating past customers is one piece of a bigger plan. At Amplified Marketing, our Growth Partnership runs paid ads and SEO to bring in new leads, with a dedicated SDR who follows up with every lead and books the ones who are ready. Reactivating past customers is one feature inside that.

    The reason why we build it this way is that your old list shrinks every month. New leads keep the list growing.

    FAQ

    Does database reactivation actually work?

    Yes, it can. Published cases show bookings from old lists in HVAC, plumbing and dental, usually in the low single digits as a share of the list. Most of those numbers come from companies selling the service and there is no neutral industry benchmark, so judge it on your own list and your booked jobs.

    What results are realistic for an HVAC or plumbing company?

    Published cases land in the low single digits as a share of the list. For example, one marketing agency's published case write-up reported that an HVAC and plumbing contractor sent to 5,000 database contacts and booked 119 appointments, about 2.4% of the list. Results vary by business and list.

    Why do dental practices see higher numbers?

    A checkup is an easy yes. One marketing agency's published case write-up reported that a UK practice texted 800 lapsed contacts and 61 booked. Results vary by practice and list.

    How old is too old for a lead?

    One marketing agency's published write-up reported that contacts up to 24 months dormant reliably produce bookings, and contacts past 36 months rarely justify the opt-outs.

    Is booked the same as paid?

    No. One marketing agency's published case write-up reported an HVAC and plumbing case where 119 bookings became 29 completed jobs. Track replies, booked, showed and paid.

    Can I text my whole old list?

    Not always. It depends on consent. Read our US and Canada guides first, and check with your lawyer.
