Sometimes it is not possible to deliver the emails and for this reason they return to the sender.
Bounce rate refers to the ratio of emails that return to the sender with an error message to the total number of emails sent.
There are 2 types of bounce:
Don’t forget that the hard bounce rate is the most important: it should always be 0%!
The best solution is to use a system that automatically eliminates addresses that generate hard bounces to optimize deliverability: this is the case of Brevo (ex Sendinblue).
5 – Spam rate:
Spam rate (%) = number of spam reports / number of emails *100
The spam rate is the percentage of reports as spam (declaration of unsolicited email) generated by your campaign.
For example : if you send an email to 100 contacts and 2 of them report it as spam, the spam rate will be 2%.
Spam rate is the statistic that has the greatest impact on the delivery of your campaigns.
In fact, if your campaigns have a spam Belgium Phone Number List rate of more than 0.1%, you could be classified as a spammer by ISPs.
To prevent this from happening, Brevo (formerly Sendinblue) automatically blacklists contacts who unsubscribe and contacts who have clicked on “Report as Spam”.
