    Bounceless

    Bounceless

    Bounceless

    Simple email verification to improve deliverability and boost email marketing metrics. You might not think much about your emails' bounce rates, but they could actually determine how many people see your emails. Internet regulators (such as ISPs and anti-spam groups) set limits for bounces, spam complaints and unsubscribe requests. If you send campaigns to inactive users and exceed these benchmarks, you will show up lower in inboxes and could even have your account suspended by your ESP. All companies that send email campaigns are assigned a sender reputation score. It's a bit like a credit score. If you send a lot of bounced or unwanted emails, this will leave a negative mark on your sender history. Also, just like credit history, once your reputation drops, it can be tricky to build it up again. Verifying your list means that you'll no longer send to dead email addresses.

Next time a website asks for your email address, give an alias instead of your real email. Emails sent to an alias are forwarded to your inbox without the sender knowing anything. Just hit "reply" if you want to reply to a forwarded email, the reply is sent from your alias and your real email stays hidden. You can also easily send emails from your alias. Quickly create an alias on the go. Sign up for a newsletter, and create a new online account with a click. Built upon open-source technology, all SimpleLogin components are also open-source. Not only can an alias receive emails, but it can also send emails. An alias is a full-fledged email address. Manage your aliases on the SimpleLogin website or on our Chrome, Firefox, and Safari extensions. Or on your phone with Android (Play Store, F-Droid) and iOS apps.
