Tired of spam and being tracked online through your personal email address? Email aliases are the solution. SimpleLogin provides you with a different anonymous email address (aka email alias) whenever you sign up for a new online service, allowing you to hide your personal email address from spammers. Emails sent to an alias are forwarded to your personal inbox. Want to reply to a forwarded email? Just hit reply and the response will be sent from your alias, keeping your personal address hidden. Not only can an alias receive emails, it can also send emails. An alias is a full-fledged email address. You can create a new alias when subscribing to a newsletter, signing up for a new account, or giving your email to someone you don't trust. If you receive spam to that address, simply disable the alias. When you give away your personal email online, there is a good chance it will end up in the hands of a spammer or hacker. SimpleLogin acts as a firewall to protect your personal inbox. Over 2 million SimpleLogin aliases have been created, making SimpleLogin one of the world’s best-known email alias services. --- Why SimpleLogin? - Generous free plan: unlike other alias services, you can create up to 10 aliases using the free plan, and there's no cap on bandwidth or the number of replies and sends. We also offer a 7day free trial of our premium service, that includes all advanced features, when you sign up. - SimpleLogin is the world’s most advanced email alias service, supporting multiple mailboxes, PGP encryption, and in-app alias management. - 100% open source and independently audited for security. SimpleLogin is verified to be secure and reliable. - Private by default. SimpleLogin forwards your emails, but does not save them. We use secure infrastructure in Switzerland, operated by Proton Mail, the world's largest encrypted email service. With a premium plan, you can: - Add your own domain and create aliases such as reddit@my-domain.com or twitter@my-domain.com. You can also enable catch-all email addresses for your domain. - If you don't have a domain, use a subdomain provided by SimpleLogin instead. - Send emails from aliases: not only can you can reply to a forwarded email, you can also initiate a new conversation from your alias. - If you have several mailboxes, you can add them into SimpleLogin and choose which one to use when creating an alias. - If your mailbox supports PGP, enable PGP on SimpleLogin, and emails will be encrypted by SimpleLogin before being forwarded to your mailbox. What others say about SimpleLogin: “SimpleLogin is a comprehensive disposable email address solution that covers just about every conceivable feature, and it’s easy to use”.
