By actively monitoring sender reputation, you can enhance deliverability and ensure that the emails reach the inbox. In this article, we will explore the intricacies of email sender reputation and provide detailed insights into how to build and maintain a strong reputation.
What is Sender Reputation?
Email sender reputation is a score that ISPs use to decide the deliverability of email. The score calculation relies on the sending history, engagement rates, spam complaints, and bounce rates. Maintaining a good reputation means inbox delivery to the intended recipient, whereas a poor reputation means blocking or transferring to the spam folder. Having a positive sender reputation is not just about ensuring that the mails reach the recipient but also about cultivating trust and credibility with your recipients. It suggests that you are a reliable sender who wishes to establish a relationship by following best practices while respecting your subscribers’ preferences.
5 Key Ways to Improve Sender Reputation
Here are some of the ways you can improve email sender reputation:
- Warm up your email domain
- Maintain mailing list hygiene
- Offer an easy way to unsubscribe
- Use double opt-ins
- Maintain proper authentication protocols
Warm Up Your Email Domain
Email warm-up is an important step in developing a good sender reputation and enhancing deliverability. Mailgo’s email warm-up feature significantly improves the sending volume from new domains, replicating human behaviour and developing trust with email providers. This process helps in avoiding the unpredictable spikes in email activity that could affect spam filters and result in blockage.
Maintain Mailing List Hygiene
Check your email list often and find out invalid addresses, spam risks, and lost subscribers. This reduces the bounce rate and augments your open rate. These metrics definitely help in improving the email sender’s reputation.
Offer an Easy Way to Unsubscribe
Do not abuse complaints by allowing readers an easy way to unsubscribe at any time. It will be hard to see them leave, but it is better than waiting for them to mark your email as spam.
Use Double Opt-ins
Taking permission from your subscribers to check their emails before adding them to your mailing list shows your responsible behaviour. However, this additional step helps in verifying that the email addresses on your mailing list are valid. Furthermore, you allow your users to give consent that they actually want to continue their relationships.
Maintain Proper Authentication Protocols
Before sending the messages, ensure that you have your SPF, DMARC, DKIM, and BIMI records available. These authentication protocols are the identity cards that show your authenticity. The authentication records ensure that you can carry out your activities and land in your subscriber’s inbox.
Importance of Email Sender Reputation
The quality of the sender’s email reputation determines whether the user’s mailbox provider will direct all the sent emails to the user’s inbox or whether the messages will be dropped into the spam folders. On the other hand, when the recipients interact with your emails, your sender reputation will improve. Hence, future messages may reach the inbox effectively. Reportedly, half of the users check the spam folder of their personal inbox every day. Therefore, the aim of the organizations is to reach the email inbox, where sending reputation is the key factor.
What Determines Your Sender Reputation?
It is not just a single action that determines sender reputation. Instead, the sender reputation comprises IP reputation and domain reputation over time. IP reputation depends on the IP address where the email is being sent. If you are using shared IP address, other senders may influence your reputation. Whereas, you are liable for your IP reputation if you are on a dedicated IP address. The domain reputation is dependent on the domain where you send mail. Like IP reputation, the domain reputation is influenced by the email you send from the platform.
