Every agency has a forgotten list somewhere: old spreadsheets, a previous CRM, contacts saved on agents' phones. Hundreds of people who once looked for a home, asked about a rental or requested a valuation, then went quiet. Some of them will have a fresh need today. Reactivation means reopening the conversation with that list.
But calling or messaging an old list is regulated almost everywhere. This article is not legal advice; it sets out the general framework. Please review your own situation with a qualified adviser before you launch a campaign.
Two layers of rules: data protection and marketing consent
The first layer is data protection: how personal data was collected, for what purpose, and how long it is kept. In the UK and EU that is GDPR; in Turkey it is KVKK, Law No. 6698 on the Protection of Personal Data. Both require you to tell people how their data is used, to stay within that purpose, and to have a valid legal basis, which for marketing is often consent.
The second layer covers marketing communications specifically. In the UK, PECR sets rules for marketing calls, texts and emails, including screening against the Telephone Preference Service and stricter rules for automated calls. In Turkey, consent for commercial calls, SMS and email to individuals must be recorded in İYS, the national Message Management System, and people can withdraw it there at any time. In every case, having someone's number is not the same as having permission to market to it.
Holding a phone number doesn't give you permission to use it for marketing.
Step 1: Clean and classify the list
- Merge duplicates and remove missing or invalid numbers.
- Record where each contact came from: lead form, office visit, phone call, portal.
- Mark which channels each person has consented to: calls, SMS, email.
- Permanently suppress anyone who has asked not to be contacted.
Step 2: Check consent status
Compare the list with your consent records and, where applicable, the relevant national registers. Contacts with valid consent can be included. Those without it should not receive marketing contact. The way to win that group back is to invite them to opt in again through a channel where you are allowed to reach them, such as a form on your website or an in-person visit.
Step 3: Set out identity, notice and calling hours
Every call or message should say clearly who you are and why you're getting in touch. People must be able to opt out easily, and that request should be recorded immediately. Calls should be made within reasonable, pre-agreed hours; ringing late in the evening or very early breaks both the rules and good manners.
Step 4: Lead with value
A reactivation message should open with something genuinely useful, not sales pressure. A few approaches that work:
- Sharing new listings in the area the person was looking in
- Offering a homeowner a free valuation in today's market
- Asking a past tenant enquiry whether they are still looking
- Letting an investor know a new development has launched
Avoid inflated claims. Phrases like “guaranteed growth” or “once-in-a-lifetime opportunity” damage trust and can create problems under consumer protection rules.
Step 5: Start small
Rather than calling the entire list in one day, start with a small batch. In a voice-agent reactivation campaign, the assistant introduces itself as the agency's assistant, asks about the person's current plans, books an appointment if they're interested, records it if they aren't, and ends the call politely. Review the first batch, refine the script, then scale up.
Step 6: Log every outcome in the CRM
Each conversation's outcome belongs on the contact record: interested, not interested, call back later, wrong number, do not contact. Interested contacts enter the pipeline as new opportunities and a task is created for an agent. Do-not-contact requests are flagged permanently and excluded from future campaigns.
Compliance is a signal of trust, not a cost
Reactivation done with consented contacts, a clear identity and a respectful tone reminds people of your agency in a positive way. A campaign run without permission might produce a few appointments in the short term, but it brings complaint and reputational risk with it. Set up properly, your old list becomes a valuable source of new conversations that costs nothing in ad spend.
