What is Double Opt-In?
Double Opt in (DOI), otherwise called Confirmed Opt in (COI), is a membership procedure when subscribers join by means of your membership form, at that point get an email with a connection they need to snap to affirm that they need to get messages from you. The new email address is just added to your postage information simply after the email address client clicks an affirmation connect in a membership initiation or pick in affirmation demand email that is sent to them after they were select in by means of a structure or checkbox.
What is Single Opt-In?
Single Opt in (SOI) is a membership procedure where a supporter’s sign up by means of a membership structure is quickly added to your email list. That is, another email address is added to your mailing list without requiring the client affirmation of that email address. They’ll begin getting your messages straight away purposely and energetically picked in.
Difference between Opt-in/Single opt-in and Double opt-in
1st case: Let’s say you have built a page.
You are offering a free e-book in exchange of visitor’s name and email. Once the visitor fill up the form and clicks on the download button, he will be redirected to another page where he would be able to get link to download e-book
Along with this redirection, the visitor would also receive one automated email which would be acting like thank you email for visitor taking an action on your web page
2nd case: Let’s say you have built another page.
You are offering a free video course in exchange of visitor’s name and email. Once the visitor fill up the form and clicks on the download button, he will be redirected to another page where he would have a message quite similar to the one mentioned below:
Thank you for entering your information. We have sent you an email to confirm your details & subscription. Please check your email with subject line…..
Along with this redirection on confirmation message web page, the visitor would also receive one automated email which would be asking visitor to click on the link inside the email to confirm access of video course.
Once the visitor click the link inside the email he/she would be redirected to your web page where the visitor will now finally have access to the offer + the visitor would receive an acknowledgement email(Auto responder) having the video link as well.
If we talk about the activity done by the visitor to get access to video course, then we can say he/she did two activities which is filling out the form and confirming the details by clicking on the link in the confirmation email.
So let’s summarize both the cases:
We can say that, 1st case where the visitor did only one activity to avail the value provided on ’s webpage is called opt in or single opt in and 2nd case where the visitor did two activities is called double opt in.
Email address on (single) opt in list are not confirmed. Anybody can submit anybody’s address to the list, and it will be there until it is unsubscribed.
On double opt in all the email addresses must be confirmed before they are added.
a request for confirmation is sent to the submitted address and address owner must take some action to confirm that s/he is owner of the email address & the address is working and s/he indeed wants to subscribe
Most often the confirmation action is as simple as replying to the confirmation request or clicking on a link
