The sender's reputation plays a fundamental role in the success of your email deliverability. It is the assessment of the level of trust that email service providers place in your identity as a sender. To establish this reputation, email services use sophisticated algorithms that analyze various positive and negative signals. The sender's reputation determines whether your emails will be delivered to the recipient's inbox, considered as spam, or simply blocked.
Criteria influencing your sender reputation
Reputation of the sending IP address
Your sending IP address, which is assigned to your email sending server, plays a crucial role in the assessment of your reputation. The main indicators taken into account are:
Presence on blacklists: Certain organizations maintain blacklists that record IP addresses associated with spam or suspicious activities. If your IP address appears on one of these lists, it will have a negative impact on your reputation.
Deliverability history
Email services review your deliverability history to assess the quality of your past sends, such as bounce rates, complaints, and recipient behavior.
Domain name reputation
In addition to the IP address, the reputation of your domain name, used in the sender address, is also evaluated. The reputation indicators for the domain name include:
Configuration of DNS records
Email services verify whether your domain name is correctly configured with SPF, DKIM, and DMARC records. These records help to prove the authenticity of your emails and to prevent identity spoofing.
Domain name history
Email services review the history of your domain name to detect frequent ownership changes or suspicious practices associated with it.
Reputation of the email footprint
The fingerprint of your emails refers to technical characteristics such as the structure of the HTML code, links, and headers. The criteria influencing your email fingerprint reputation include:
Recipient engagement
Email services assess the open rate, click rate, and interaction with your emails to determine their relevance and the level of engagement from recipients.
Complaint rate
Complaints flagging your emails as spam or unwanted will have a negative impact on your sender reputation. A high complaint rate indicates a lack of interest or consent from recipients.
Anti-spam filters
Email services analyze the characteristics of your emails to detect signs of spam, such as suspicious keywords or misleading links.
Compliance with authentication standards
The compliance of your sender domain with authentication standards, such as SPF, DKIM, and DMARC, is also essential. These authentication protocols help prove the authenticity of your emails and prevent identity spoofing. The absence or incorrect configuration of these records can harm your reputation.
Hygiene of your lists
The quality of your subscriber list plays a critical role in maintaining a good sender reputation. Here are some important points to consider:
High-quality subscriber list
Ensure that your list contains only individuals who have explicitly consented to receive your emails. Avoid purchasing or renting lists, as this can damage your reputation. Favour safe practices such as collecting contacts through a form on your website and implementing a double opt-in system.
Incorrect and inactive addresses
Invalid or inactive email addresses lead to hard bounces, which can have a negative impact on your reputation.
Presence of spamtraps in your contact lists
Spamtraps, also called spam traps, are email addresses used specifically to detect senders who do not comply with best practices. Sending emails to these addresses leads to a decrease in your sender reputation.
Behavioral indicators

Clicks
