The drop in UCEPROTECT listings for SparkPost and Sendgrid is likely due to a combination of factors. These include: improvements in email marketing practices and spam resolution by SparkPost and Sendgrid leading to a cleaner IP reputation, potential changes in UCEPROTECT's listing criteria (possibly influenced by pressure from larger ESPs or internal policy adjustments), and improved email authentication practices (SPF, DKIM, DMARC). It's also suggested that UCEPROTECT's practices are questionable and their motivations unclear. While some believe UCEPROTECT's 'pay-to-delist' model might have been a factor, others maintain no payments were made. The automatic delisting mechanism of UCEPROTECT, along with consistently practicing good email hygiene, also contribute to the reduced listings. Furthermore, the significance of UCEPROTECT listings themselves is questioned by some.
8 marketer opinions
The drop in UCEPROTECT listings for SparkPost and Sendgrid IPs could be attributed to several factors. These include: improved email marketing practices and spam resolution by SparkPost and Sendgrid, UCEPROTECT changing its listing criteria (potentially due to pressure from larger ESPs), the unreliability or questionable practices of UCEPROTECT's listing policies, or even possible negotiations or payments made by the ESPs to influence listing thresholds or be removed. Consistent email hygiene practices, like stricter signup verification and removing inactive users, also contribute to better IP reputation and reduced blacklist appearances. Some suspect a policy reversal or temporary adjustment from UCEPROTECT.

3 expert opinions
Experts suggest several reasons for the drop in UCEPROTECT listings for SparkPost and Sendgrid. One explanation is an automatic timeout mechanism or a change back to a previous Level 3 listing algorithm. Another reason is that paying UCEPROTECT only provides temporary relief as relisting occurs with subsequent spam trap hits. Finally, UCEPROTECT's questionable practices and unclear methods imply that the listing changes may stem from internal policy adjustments or external pressure.
