We just rolled out a major update that will now allow you to collect phone numbers through our entry forms without having to also ask for an email address. As more and more companies push to grow their SMS lists, we understand there is not always a need to ask a user for their email address. You can now build any campaign and ask for just a phone number, or ask for more information like phone, name, and address, without requesting an email address.
Soon we will also be rolling out 3rd party integrations with a number of SMS providers that you will be able to connect to in order to pass phone numbers through to your SMS lists.
