Unless your wedding fair organiser has implemented a system to get explicit consent for each exhibitor to contact the couples registering for the event, you'll be in breach of GDPR. If you contact anyone through the mail list and the fair organiser will be in breach if they produce and circulate a non-compliant mail list.
Our top tips on getting around the challenge:
1. Ask the fair organiser how they are planning to get consent and make your own judgement as to how many couples will sign up to receive information from you. The regulations discourage signing up being a pre-requisite to receiving a service so won't look favourably on fair organisers refusing entry to couples not giving consent.
2. If a follow-up call or email is an essential part of your marketing, take responsibility for your own GDPR compliant list by asking permission from couples to contact them after the fair. Consent can be verbal but it is safer to put together a simple GDPR compliant form.
3. Not exhibiting? Couples are less likely to give consent for other businesses to contact them so you'll need to be at the fair if that mail list is important to you. If you aren't exhibiting in person they'll assume you aren't that relevant to them.
4. Don't pass on a mail list to another business or another part of your business, or both will be in breach of the regulations.
5. Consent is specifically for the purpose agreed. A couple that has given consent to hear from you just in relation to their wedding shouldn't be added to your marketing mail list for other products or services without consent.
Remember, the regulations are great news for businesses that put their customers first and only send them relevant information. Your message won't now get lost in an overcrowded mailbox!
