How can you impact your email opening rate?
Prospecting by email can be a very good tool for your commercial development. However, it can also become the opposite if you do not take into account a crucial point: The reputation of your domain name. Indeed, it has a strong impact on your email opening rate.
At Prospilot, our team take this point very seriously, which can completely change the purpose of your prospecting.
Ps: Go all the way to the bottom, you'll find a tip 😉

What is the email opening rate?
The email open rate is a measure used in the field of email marketing to assess the effectiveness of an email campaign. It represents the percentage of recipients who opened an email compared to the total number of emails sent. Here's how it's generally calculated:
Open rate = (Number of emails opened/Number of emails sent) × 100
A high open rate may indicate that the subject of the email is attractive and that the recipients are interested in the content of the email. However, it is important to note that this rate does not measure engagement or actions taken after the email was opened, but only the fact that the email was opened.
Reputation: a key point in your email opening rate
What is reputation?
When we talk about reputation, we think directly of the public's opinion of someone or something. However, there is a second definition that is specific to our profession and which, ultimately, derives from the first. In prospecting, the reputation of your domain is a score that determines how email systems decide what will be accepted in your prospects' inboxes.
When you create an email campaign, there are therefore several factors to take into account so that your email address does not lose its reputation and to avoid ending up in spam, in other words, the place where no one ever consults their emails.

The status of email addresses
To impact your commercial development, you will regularly go through email campaigns. You will therefore, first of all, establish a database of the people you want to contact to offer them your offer. To ensure good deliverability, you need to know the status of the email address. By choosing emails with a secure status, you will increase your deliverability and maintain your reputation.
Each email has its own status and this can impact your commercial development both positively and negatively if you are not careful. So here are the various existing statuses:
- Safe: Valid address, active and ready to receive emails.
- Role: Address linked to a function, can be managed by several people.
- Catch-All: Server setting that accepts all emails (even invalid ones).
- Disposable: Temporary addresses, often abandoned after use.
- Inbox Full: These email addresses can no longer receive messages.
- Spam Trap: Addresses created to catch spammers.
- Disabled: Addresses that are no longer in use.
- Invalid: Addresses that do not exist, often due to an error or a typo.
In order to optimize your deliverability and at the same time your commercial development, you will therefore favor “Safe” and “Role” emails. By neglecting this step, you risk sending emails every week in “Spam Trap” and to invalid addresses that will lower the reputation of your email.

How to do it?
In order to check your email addresses there are several tools that will be useful to you:
- Bouncer : It allows you to check the status of an email address or several addresses at the same time.
- Neverbounce : This one has the same purpose.
- Scrubby : It will allow you to check all the Catch-all addresses for which you are not sure if they are valid. The delay is a bit long but well worth it!
With these tools you will only keep email addresses that are secure and that will not have a negative impact on the reputation of your domain name.
