Reputation ManagementEmail Reputation is Essential for Transactional Emails

To ensure that emails actually end up in the recipient’s inbox, senders must meet a wide range of technical requirements. Read more here about why good email reputation is important for effective transactional emails and how companies can master the challenges of reputation management with Retarus.

Transactional emails are created during a business process. They are sent automatically from software systems once the customer has performed an action. This is different from email marketing, which is purely for promotional purposes. Marketing emails originate solely from the provider and are not sent as part of a business process. A transactional email is used to communicate with the customer. Examples include the following:



To confirm the subscription to a newsletter



To confirm that a product or service has been ordered



To send an invoice, receipt, or payment reminder



To notify a customer about a delivery or a new message in the customer portal



To notify a customer of a password reset or other account transactions

Users take these types of transactional emails for granted. They are even expected as proof that a transaction was successful. Retarus Transactional Email allows companies to send large volumes of automated emails. Comprehensive reputation management guarantees a high delivery rate.

What Are the Challenges When Sending Emails?

Sending transactional messages via your own email servers puts a strain on the infrastructure. Additionally, it carries the risk that the company’s own IP address will end up on a blocklist. Furthermore, it is difficult to comply with the constantly changing technical requirements that ensure a good email reputation and thus a high sender score.

Why Is Email Reputation so Important for Transactional Emails?

If the sender’s reputation is not good, it’s possible that the messages will not reach customers’ inboxes as desired. Instead, the emails end up in the spam folder, quarantine, or in a worst-case scenario, are not delivered at all. If this happens with transactional messages, user satisfaction and trust suffer. For example, customers do not know whether an order has been received, when to expect delivery, or perhaps never receive an invoice for a product they already purchased.

For the company sending the emails, this means additional costs and extra work. In addition, the reputation and image of a provider is negatively impacted if emails are classified as spam and are not delivered.

What Is the Significance of the Sender Score?

A sender’s email reputation is determined by the reputation of the sending IP address and domain, as well as the quality of the email content. Internet service providers (ISPs) determine the sender reputation and trustworthiness.

The sender reputation is indicated, for example, by a sender score on a scale of 0 to 100. The higher the score, the better the reputation of an IP address when compared to others. If the sender score is high, most emails end up in the recipient’s inbox. If the number is rather low, the sender’s emails are likely to have high bounce rates, high block rates, and low open rates.

Before sending emails for the first time, senders should be aware of their scores, because optimizing a bad score takes some time. Senders can check their IP address at www.senderscore.org. Professional providers for transactional emails, like Retarus, monitor this score and implement countermeasures together with their customers through active reputation management to prevent the score from deteriorating.

If your Sender Score is below 70, you should work on your sender reputation.¹

You are probably already aligning yourself with industry standards and are not far from an optimal reputation.¹

Your reputation as an email sender is at an appropriate level.¹

What Factors Affect Email Reputation?

Here are the most important factors affecting transactional email deliverability

Frequency of emails

The frequency of emails sent has a noticeable impact on email reputation. Senders should send regularly and on a set schedule.

Marking the sender's emails as spam

The more contacts that mark a sender’s email as spam, the worse the email reputation.

Fluctuating sending volumes

The number of emails sent should remain roughly consistent. Sending volumes that fluctuate greatly have a negative effect on email reputation. The sending volume is always related to other index values. For example, the sender’s reputation improves the fewer complaints there are for the emails sent.

Reader interaction

Reader interaction, meaning if emails are opened and links in the emails are clicked, also has an impact on reputation.

Email undeliverability

If the distribution list contains contacts that are no longer valid, the result is more than just a high bounce rate. For ISPs, they are also an indication of poor address quality at the sender’s end. Senders who regularly send messages to invalid email addresses can be flagged as spammers. The sender score metric takes into account how often emails cause a bounce². This is why maintaining one’s own distribution lists and databases is of great importance.

Blocklists and Allowlists

Blocklists contain IP addresses that have been reported as known spam senders. If a company’s IP address ends up on a blocklist, it can no longer send any messages at all. In such cases, professional providers of transactional email services help their customers to get off the blocklist as quickly as possible.
In addition, certification with the Certified Senders Alliance (CSA)³ ensures allowlisting for major ISPs. In order for senders to appear on the CSA’s positive list, they must fulfill certain defined and independently verified criteria. If senders are allowlisted, emails sent with the recipient’s consent by reputable providers can actually reach the customer. If not, there is a risk that the emails will already be sorted out by spam filters on the provider’s servers.
