When it comes to email marketing businesses are concerned on whether they should use a single or double opt-in option. Some will say that using a double opt-in makes them lose subscribers – after all, how many people really take the time to click a link to confirm their subscription? That may be a good argument but it’s really a weak one if you think about it.
You work hard to get people to opt-in to your mailing list. Once you get them on your list the last thing you want is your emails to end up in the dreaded spam folder.
