A tiny mistake in your email marketing campaign can lead to a bad impression and unsubscription from your customers. Here is a checklist for you to review before you send out your email campaign:

  2. Do you provide a plain text version of your email?
  3. Do all the images have alt tags?
  4. Do all your pictures have links and are they linked correctly?
  5. Do you personalize each email?
  6. Do you provide an unsubscribe option in your email?
  7. Do you explain who you are and why your customer should trust you at the beginning of the email?
  8. Are you tracking the clicks in your email using tools like Google Analytics and
  9. Have you cleaned up your list (bounce-backs and unsubscribers from your last email campaign?
  10. Have you tested how your email look in different web email platforms and email clients?


Based on CAN-SPAM laws, it is required that email marketers should provide recipients an option to opt out or unsubscribe from the list. It is not only a matter of etiquette but also a matter of the law that you make this opt-out process as easy as possible.

If you are using email marketing software like 1and1Mail, there are 2 ways to automate this opt-out or unsubscribe process:

I. Insert an unsubscribe email link in each email. e.g. “To unsubscribe, please send an email to”. Check this unsubscribe email regularly and batch remove the unsubscribers from your address book.

In 1and1Mail Email Template Editor,

1. Click “Insert” menu and select “Link”.
2. Select “(other)” in Type.
3. Type “ unsubscribe me from your mailing list.” in URL.

1and1Mail HTML Editor

II. Insert an unsubscribe link in each email that direct the recipient to your website to complete the opt-out process. e.g. “To unsubscribe, please click” The landing page should be able to capture the link parameter and save the email address for further process.

In 1and1Mail Email Template Editor,

1. Click “Insert” menu and select “Link”.
2. Select “http:” in Type.
3. Type something like “[%Email]” in URL. ([%Email] is the Macro text that will be replaced by the real recipient’s email when the mass emails are sent out through 1and1Mail. When the recipient click this link, the landing page should be able to capture the “?unsubscribe=[%Email]” parameter.)
