How to reconcile opt-outs before contacting old leads

01

Collect the decisions, not just the addresses

List the systems that can receive or store requests: campaign tools, the sales system, shared inboxes, call notes and any outside sender. For each contact, collect the channel, purpose, preference or objection, source and date. A suppression record is a minimal record used to prevent unwanted contact. It is not a list to market to.

Match records using reliable identifiers, and put uncertain matches in a review queue. An address shared by several people or a changed address may need human review. Limit access to the suppression data and preserve enough information to prevent a repeat send, following your retention policy.

Rules vary by jurisdiction and channel. They also depend on the recipient and message purpose. Check applicable requirements and documented permission or another applicable basis before contact. A prior purchase or inquiry does not automatically authorize every marketing message. For UK electronic-mail marketing, consult the ICO guidance, including its distinction between subscriber types. For other channels or recipients elsewhere, use the applicable local rules and sources.

02

Resolve conflicts conservatively

Suppose a sales record says a prospect asked for a quote six months ago, but the marketing system records an email unsubscribe last month. Suppress marketing email for that address and stop any queued campaign. Investigate the purpose and scope of the request before deciding whether another channel or a requested transactional response is appropriate. Do not assume the earlier inquiry overrides the later objection.

If one record says permission was granted after a stop request, inspect the actual wording, date, channel and source. A new checkbox or a verbal note may not establish permission for every purpose. Hold the contact until the responsible reviewer resolves the conflict under the applicable rules. Record the decision and supporting evidence rather than deleting the stop history.

For a request to stop all contact, apply that scope across the relevant systems. A channel-specific objection may have a different scope. Record the exact words and seek review when unclear. Give the recipient a working way to communicate preferences and route replies to a named owner.

03

Make suppression part of every send

Before exporting a campaign, screen the proposed audience against the current suppression records. Check again at sending time, because preferences can change after the list was prepared. Propagate new requests to all relevant senders and cancel scheduled follow-ups. Document who owns each update and how failures are escalated.

Reconcile totals: records selected, suppressed, held for uncertainty and approved to contact. Sample each group against its source. If an outside provider sends on your behalf, agree how it receives updates and confirms removal. Review a small sample after the send and correct any gap before another campaign.
