Is there a web app to collect emails?
I made a landing page for my startup, and I've so many things to do, so I'd prefer to save up energy and not setup Mailgun, a separate db table for emails, form validation and all that. Maybe there is a service that provides an iframe for email submission so that I could slap it on my landing page, and get my future users' emails in Airtable or something?
Most email marketing tools (like mailchimp & mailjet) include form builders to collect sign-ups.
You could export these lists manually or even set up an integration service like zapier to get them into airtable.
Not that I know of, but definitely something I'm gonna put on my 'future project ideas' list.
