The Organization Whose Entire Business Model Depends on a Database It Cannot Keep Clean
Trade associations and professional societies exist to serve their members, and everything they do -- advocacy, education, networking, standards development, certification -- depends on knowing who their members are and being able to reach them. The membership database is not just a list of contacts; it is the operational backbone of the association. Dues invoices are generated from it. Event invitations are sent to it. Advocacy alerts and calls to action go to it. Committee appointments come from it. The annual report's membership count comes from it.
Yet association membership databases are notoriously difficult to maintain. The association does not control the contact information in its database -- the members do, and members rarely update their information proactively. A contact person who leaves a member company does not call the association to provide a new contact. A company that is acquired does not notify every association it belongs to of its new legal name. An individual member who changes jobs does not log into the association's website to update their employer and email address. The association discovers these changes only when a dues renewal notice bounces, an event invitation goes to a person who left the company two years ago, or a committee chair tries to reach a committee member who no longer works in the industry.
The data quality problem compounds over time. An association that does a thorough database cleanup in January may find that 15-20% of its contact records are outdated again by December, simply through the normal churn of people changing jobs, companies being acquired, and contact information going stale.
Contact Person Succession Tracking
The most common data quality issue in association membership databases is the departed contact person. Trade association memberships are typically held by the company, but the membership record lists an individual contact person who serves as the liaison between the company and the association. When that person leaves the company -- retires, takes a job elsewhere, gets promoted to a role that no longer involves association participation -- the membership record becomes orphaned. The company is still a member (its dues are still being paid, often by automatic payment), but the contact person listed in the database no longer works there.
The orphaned contact problem manifests in several ways. Emails sent to the departed contact's work email address bounce (if the email has been deactivated) or go unread (if the email has been forwarded to a general inbox that nobody monitors). Dues renewal notices reach someone who no longer has authority to approve the payment, leading to inadvertent lapses. Event invitations and advocacy alerts reach nobody, which means the member company gets no value from its membership, which makes it more likely to lapse when someone finally does review the invoice.
Export your membership database from your association management system (AMS). Upload to Email Extractor to extract and validate email addresses across all member records. Email addresses that bounce or are identified as invalid are strong indicators of departed contacts who need to be replaced.
For member records with invalid email addresses, the next step is finding the current appropriate contact at the member company. Visit the member company's website and check the leadership or team page for the person most likely to serve as the association contact (typically someone in a role similar to the departed contact -- VP of operations, director of regulatory affairs, government relations manager, or similar, depending on the association's focus). Save the company website team page as HTML and upload to Email Extractor to extract the new contact's email address.
Corporate and Individual Membership Overlap
Many associations offer both corporate memberships (the company is the member, and all employees receive member benefits) and individual memberships (the person is the member, regardless of employer). When a company has a corporate membership and some of its employees also hold individual memberships, the database contains overlapping records: the company record with its designated contacts, and the individual records for each employee member.
This overlap creates duplication in communications (the employee receives association emails as both a corporate member contact and an individual member), confusion in dues processing (the employee may receive individual dues invoices even though their company membership already covers them), and inflated membership counts (the association reports both the corporate membership and the individual memberships as separate members, overstating the actual number of unique people and organizations represented).
Export both corporate and individual member records from your AMS. Upload to Email Extractor for cross-category deduplication. Records that share the same email address or the same email domain (suggesting the individual member works at the corporate member company) are candidates for overlap resolution. The resolution may involve converting the individual membership to a corporate contact designation (if the company's corporate membership already covers the individual), maintaining both memberships but suppressing duplicate communications, or contacting the individual to determine their preferred membership type.
Multi-System Record Reconciliation
Large associations maintain member data in multiple systems that may not share a common identifier or synchronize automatically. The AMS holds the official membership record. The event registration system (Cvent, Eventbrite, a custom registration platform) holds event attendance history and contact preferences. The advocacy platform (VoterVoice, Quorum, Phone2Action) holds legislator assignments and action history. The learning management system (LMS) holds continuing education and certification records. The online community platform (Higher Logic, Discourse, a custom forum) holds profile information and engagement data.
Each system may contain different versions of the same member's contact information, collected at different times and through different forms. The member's AMS record may have their office phone and work email. Their event registration may have their mobile phone and a personal email (used when registering from home). Their advocacy profile may have their home address (for legislative district matching). Their community profile may have a different email entirely.
Export member contact records from each system. Upload all exports to Email Extractor for cross-system deduplication. The deduplication identifies members who appear in multiple systems with the same email address (strong match), the same name (weaker match that needs manual verification), or the same organization (potential match if the name has changed).
After identifying cross-system matches, designate the AMS record as the master record and merge the most current contact information from each system into it. Establish a data governance process for keeping the master record current: designate the AMS as the system of record, configure other systems to pull contact information from the AMS rather than collecting it independently, and implement periodic reconciliation checks (quarterly) to identify and resolve discrepancies that accumulate between reconciliation cycles.
Lapsed Member Re-Engagement
Members whose memberships have expired and whose contact information has gone stale represent a re-engagement opportunity. Lapsed members are easier to win back than new prospects because they already understand the association's value proposition, have relationships with other members and staff, and made the decision to join once before.
The challenge is reaching them. Their work email may be invalid (if they changed employers since lapsing), their phone number may have changed, and their mailing address may be outdated.
For lapsed members with invalid contact information, search LinkedIn for the member's name and former employer. The LinkedIn profile typically shows the member's current employer and title, which provides the information needed to find current contact details. Save the LinkedIn profile page as HTML. If the profile includes a visible email address, upload to Email Extractor to extract it. If not, visit the current employer's website to find the contact's email address.
