Removing email registration improved retention
This is not advice any startup should ever listen to.<p>The most successful and lucrative form of marketing, by far, is re-marketing.<p>That is where you take someone who signed up but is not currently a customer and you target Facebook&#x2F;Google ads specifically at that email address. I&#x27;ve seen conversion rates as high as 30% and it&#x27;s typically pretty affordable.<p>It&#x27;s such a critical part of marketing that many companies will take a loss on the initial &quot;here is our product, please join&quot; ads just so they can follow up with re-marketing in the weeks&#x2F;months to come. And because people re-use their email addresses across websites you can target them on Quora, Reddit etc as well.<p>You can&#x27;t do any of this without their email.
