Definition:

Spam Score measures the likelihood that an email will be flagged as spam, affecting its chances of reaching recipients’ inboxes.

Spam Score is a metric used to assess the likelihood that an email or message will be flagged as spam by email service providers. This score is calculated based on various factors such as content, formatting, sender reputation, and the inclusion of certain keywords or links. High spam scores can result in messages being filtered into recipients’ spam folders, reducing the effectiveness of email campaigns. Nonprofits rely on low spam scores to ensure their communications, such as donation appeals or newsletters, reach supporters’ inboxes. Monitoring and optimizing your spam score helps maintain better engagement rates and ensures that important messages are delivered successfully.

Real World Example

A nonprofit prepares a fundraising campaign using Keela’s email tools. Before sending, Keela alerts the team that their message has a high spam score due to excessive use of bold text and suspicious links. By following Keela’s recommendations—editing the content, removing flagged keywords, and verifying their sender information—the nonprofit lowers the spam score, ensuring their email reaches more supporters’ inboxes. This results in higher open and donation rates, demonstrating the importance of monitoring and optimizing spam scores for successful campaigns.
