Do you know the difference between a single and double opt-in process?  Which one should you use to win new email subscribers?  Read on for our guidance.

Single Opt-In

So this is basically a sign-up process where a user does not need to confirm that they signed up to receive email campaigns.  The user submits their email address, (and maybe some further details about their preferences), and they’re added to your email marketing database.  This can be an instant process if you use Campaignmaster Subscriber Forms.

Double Opt-In

A double opt-in requires confirmation that the subscriber has indeed signed up.  This is achieved by sending an instant email notification to the user after form submission.  This notification email requires the user to physically click on a link within the email to confirm their legitimate ownership of that email address.  What’s more by gently pushing your subscriber to check their inbox, they are also verifying their intent to receive your content. By the way Campaignmaster can handle both single and double opt-in’s easily for you.

If you’re still unsure of which opt-in process is better for you, I’ve listed the pros and cons below.

The question then is which is better? In our expert opinion, it depends on your business and the priorities you place on building a subscriber database. Probably not the straight answer you were looking for, but that’s email marketing for you!  Different processes work for different businesses.

Double opt-in will gives you a cleaner list but may be slower in terms of list growth but if you find you have high hard bounce rates due to inaccurate email data then I would suggest you opt for double opt-in.

If you want to grow a list quickly single opt-in is the obvious choice.

Still, I thought I’d share this double opt-in process from Richard James to give you further food for thought:
