Best use of an email sender reputation

email sender reputation What is an email sender’s reputation? ISPs use a numeric reputation score to rank the reliability of email senders. It’s critical to your email’s deliverability. A higher score indicates that an ISP is more likely to deliver emails to the inboxes of recipients on their network. If the score falls below a specific level, the ISP may route messages to the spam folders of recipients or even reject them entirely. Numerous variables may contribute to the score calculation, including, but not necessarily limited to:

  • The volume of emails that a company sends
  • How many receivers report the organization’s emails as spam or otherwise complain to the ISP?
  • How often do the organization’s emails get caught in the ISP’s spam filter
  • Inclusion of the organization on several blacklists
  • How many emails does your company send that bounce due to being sent to unfamiliar people or for other reasons?
  • How many recipients open, respond to, forward, and delete communications from the organization?
  • How many recipients opt out of an organization’s email list?

What is an email sender’s reputation? ISP determines which elements to use in its sender reputation calculation and how highly to weigh them when determining the reputation of each business that sends an email to some of its subscribers. A sender’s reputation score may vary depending on the ISP. If a sender owns numerous domain names and sends emails from various IP addresses, each of those domain names and IP addresses will have its sender reputation.

How do you safeguard your reputation as a sender?

It is critical to adhere to specific recommended practices to maintain the highest possible sending reputation score.

Maintain your email list: Delete invalid emails and non-responders from your list regularly. Because high bounce rates may harm your sender reputation, keeping your lists clean can help you achieve improved email delivery rates. You may check and manage your bounce lists directly from the SparkPost web app’s dashboard.

Hence, you can confirm the user’s email address and their consent to receive your emails. And never acquire an email list from a third party — if you do, you risk ruining your sending reputation.

Monitor email delivery: Keep an eye on your email delivery rates by keeping a careful eye on your bounce rates and response rates. Regular monitoring enables you to identify possible issues before they occur.

Keep an eye out for bounce codes: Hard bounces are straightforward to handle since they indicate that the address is no longer valid and should be placed on your suppression list. (SparkPost automates this process for you.) However, since a soft bounce is a transient issue that might occur for several reasons, it’s critical to examine the associated bounce code to understand how to handle that address. (SparkPost’s deliverability capabilities make a significant impact in this instance.)

Create emails that are both entertaining and clickable: Because how people engage with your messages affects your sending reputation, provide them with locations to click and reasons to open and act on your emails. If you come off as spammy, even if you follow all other rules, you might harm your sending reputation.

The last thing an ISP wants to see is a fresh sender spamming their network. The most effective strategy for establishing a positive sending reputation with an ISP is to gradually increase campaign volume week after week.

The basic line is that you should approach your sending reputation similarly to how you approach your professional reputation. Your email-sending reputation operates similarly. Protect it as though your business’s success is dependent upon it, which, in part, it is.
