  • Single Opt-in

People get to your email list after filling the registration form.  It’s much better than opt-out method, cause it excludes automated subscription, but there is one problem with this one too – somebody can use your email and subscribe you to a newsletter you don’t even know about – f.e. your husband, sister, clever talking parrot, etc. So, people may become frustrated after receiving letters they didn’t give their permission on, and send complaints on you with wishing to add you to spam filters.

  •  Double Opt-in

When somebody wants to get subscribed to your newsletter, you’re sending him confirmation email. This person should click on received link to confirm their will to be involved in this business. Using this way of subscription, people won’ blame you in spamming and one more important nuance is that only interested auditory will receive your letter, and response rate will be much higher, what will positively affect your business.
