There are various online services that let you create disposable email addresses. These are for times when you want to use an email address once then delete it or be able to delete it if spam emails start arriving.

For example:

• If you want register to download a document or brochure etc. but don’t want to get follow up sales emails
• To register on a website where you think they are likely to sell your contact details to spammers
• For someone you don’t really trust
• To be able to track which services sell your contact details

Google doesn’t offer this disposable email address service but Gmail does have a facility  to create customized emails that you can then automatically delete that you can use to identify senders and filter incoming emails, so it is a little similar to disposable email addresses.

Step 1: When asked to input your email in an online service, you add a tag to your email address e.g. instead of fredbloggs @gmail.com you could use fredbloggs+uselessemail @gmail.com

Whatever is after the + sign will be ignored by Gmail.

Emails sent to that address will appear in your inbox alongside all of the others, but with that specific tag on the end of the address, they are very easy to eliminate or block entirely.

Step 2: You can setup Gmail filters to move such emails to another folder or to delete them if you wish.
