Pop-ups for collecting your contacts’ phone numbers are the most straightforward way to start growing your SMS lists
. You can create phone number-only forms or capture both phone numbers and email addresses - the choice is yours. The best part? Other ESPs require you to store the emails of every subscriber, but with Omnisend it's enough to have a contact's phone number to start running marketing activities to this specific person. So, whether it’s just SMS, email, or omnichannel marketing you’re looking to do, you're free to choose.
