Which should you use for your email marketing: Double optin or single optin?

Email Marketers are constantly debating the worth of single optin vs double optin when it comes to building their lists. The option you select could have a profound impact on your success as an email marketer.

First… what is the difference between Single optin and Double optin as it applies to email marketing?

Single optin simply means that someone can enter any information in to a capture form and they are automatically subscribed and/or given access to the free ebook, software, etc… that is being offered by the marketer.

Double optin, by contrast, means that once the form is submitted, the person will be asked to confirm their request before they are given access to the offer. Typically, the confirmation is accomplished by having the subscriber click a uniquely coded link.

The most common argument for using the single optin method is that some email marketing practitioners believe it helps build a larger list. In terms of pure numbers, they may be right. But there is more to the picture than the raw number of prospects in your list.

The most common argument for using the double optin method for email marketing is that email marketers want to know that the prospects they are generating are:

Real humans that read their emails. Genuinely interested in receiving the information being offered.

Someone using the single optin method may think that they have 5,000 prospects in their database but may actually have somewhere around 3,000 because 2,000 are nothing more than junk emails, spam traps, or bots.

While 3,000 prospects is nothing to take lightly, consider that if 2,000 of those addresses are not valid, that means the ebook, software, download, etc… that was being offered has essentially been stolen if you did not ask those prospects to confirm before receiving your offer.

Another big issue to consider is deliverability.

If your email marketing list is cluttered with unknown or garbage email addresses, this can have a negative impact on your overall deliverability. Many email service providers will begin blocking domains that are known to repeatedly send to email addresses that don’t exist. Over time, this can result in your messages not being delivered to the real prospects that you do have. What good are those real prospects if your message can’t be delivered to them?

Some proponents of single optin hold the position that it doesn’t matter since email marketing is so inexpensive. “Why should we care if some of the email addresses in our list don’t really exist? Email marketing is so cheap anyway.”

This is a flawed perspective. Those bad email addresses could be costing you more than you realize.

Not only is your deliverability affected, meaning that your message may not be getting through to even the good email addresses, but you may be overpaying your autoresponder service provider.

AutoResponder companies like Aweber, GetResponse, Constant Contact, iContact, etc… charge on a sliding scale meaning the larger your list, the more you will pay each month.

When their system looks at your account, they see the total number of prospects. So if you have 5,000 records but only 3,000 are actually deliverable, you are paying too much.

The idea behind using technology like autoresponders and email marketing should be to help your business increase sales while reducing expenses. Using single optin to build your email marketing lists could cost you not only in efficiency but also in your pocketbook.
