Managing preferences vs implied interest
We're in the process of designing a welcome program which involves reviewing our preferences centre. The idea is that people will receive a welcome email and we'll ask them to let us know who they are and what they want to receive from us - so capturing both their interest in email/communication type (events, services, webinars etc) but also actual sector interest (related to our specific offering).
Scenario: we often mark someone as being 'interested' in a sector if they engage with content related to that sector in a certain way - i.e. clicks 3 x email and fills out 1 form for example. What if a person goes to our subscription centre and has said they are not interested in 'x' sector, but their behaviour implies they are? We'd mark them as interested in 'x' sector due to rules stated above... Is this wrong? Does any one have any best practices around this? Don't want to over complicate things but feel we should be respecting people's wishes if they have actively told us what they want to receive.
