If you're spending a lot of time and effort attending wedding fairs, it's important not to waste that by loosing potential clients who end up forgetting about you.
You can easily setup a contact form for your potential clients to fill in at your stand. With their details you can then schedule follow-up emails and WhatsApp messages in advance that'll trickle out behind the scenes until the couples are ready to book you.
If you attend regular wedding fairs at the same venue, it's easy to duplicate the details from a previous wedding fair to save you even more time.
