General

I have a blog in the dating/relationships niche and want to create an email list. Thing is, i don’t really know how to go about it. I need a bit of help with the following

  1. What is a good plug in to collect emails?
  2. Do i have to give something for free and if so what should that be? (looking for ideas)
  3. Do i need a landing page and how do i create one?
  4. How often should i be sending out emails and out of those times how many should i be trying to sell something?

Dig from sites like Tinder and Instagram where people prioritise being sexually attractive.

To create an email list, define your audience, choose an email marketing service, create a sign-up form, offer incentives, segment your list, craft compelling content, maintain consistency, and monitor performance. Comply with relevant regulations when collecting and managing email addresses.
