When you check how your emails performed, you'll see how many of your subscribers received the email, and who opened and clicked on links in your email. Also, you'll find additional information like who has unsubscribed, marked your email as spam, or whether an email address has bounced.

You know very well what unsubscribed means. And you probably have marked emails as spam yourself in the past.

But what is that mysterious bounced category?💁🏻

What does it mean when an email address 'bounces'?

When an email address bounces it means your email couldn't be delivered to that email address. The reasons for this can be among others:

  • The email address doesn't exist (typo or the email account has been closed down)
  • The email can't be delivered ( the receiving email server is temporarily unavailable, e.g. under maintenance)
  • The receiving mailbox is full (it can't receive more emails so they bounce back)
  • The receiving mailbox has auto-reply turned on (if the recipient is out of the office your emails to them can bounce)

How does Flodesk handle bounces?

First of all, before your email is sent, we have a technology that lets us check which emails will hard bounce and not send to those. So the hard bounces you're seeing won't affect your sender reputation (no action needed on your side).

A hard bounce occurs e.g. when the email address is invalid, like there's a typo or the email account doesn't exist anymore.

Soft bounces, on the other hand, won't be removed because they could be anything from auto-replies to mailbox full. The emails bounce, so they aren’t counted as delivered, but Flodesk will try resending again so we don’t remove them from your list. 

If they become hard bounces eventually, then the process above kicks in.

What about if someone subscribes under multiple emails?

We exclude email addresses that hard bounce and we don't send them your campaign or workflow emails. We do the work, no action required on your side. You're protected.

If someone subscribed with multiple emails and some bounce and some don’t, the ones that did not bounce would be kept. We have no way of knowing if it’s the same person who signs up with different emails!

Let's sum it up

Bounced in your statistics means that your email campaign or workflow email couldn't be delivered to that specific email address.

Before your email is sent, we have a technology that lets us check which emails will hard bounce and not send to those. In case of a soft bounce, we try to resend the email a bit later again.
