USING Brevo as a customer database

here is my issue, i have customers that fill out hand written forms and then they get entered into the contacts here. some customers do not have or dont write down their email address. some use the same email address as their wife, son, daughter, husband. so we have data that goes missing. on top of that we have our mailing list email here sending it out to customers who have signed in and asked for emails. we use the other list for post office mailings. how can we use Brevo without losing data.

Hi @Event , thanks for posting on this community!

I understand the specificities of your use cases, but what I am not sure to get is what you’re trying to achieve: could you please give more details about it?
