The best way to grow an email list is to do it slowly and organically, so that the contacts are really engaged and can become the top notch followers you want. Keep sending awesome and relevant content and you'll see your list grow.
Once you have your signup form link you can share it.
Already Have a List of Customers?
Even though someone is a current or past customer of yours, they may not want to receive emails from you.
Let's suppose you have a list of customer email addresses and you want to start sending them email marketing, but you don't have their permission yet. Many people mark any mail they weren’t expecting or don’t want as spam, even if they know it isn’t spam. This can cause problems for email marketers, business owners, and ESPs likeTurbo-SMTP.
Send a "Re-Introduction Email" from your regular email address (not a bulk email servic like Turbo-SMTP). Put together a personal note like you would write to a friend. Include the link to your signup form in the emails. This signup process is effective.
