For PRIVATE section requests that are submitting entries for domains that match their organization website's primary domain, please understand that this can have impacts that may not match the desired outcome and take a long time to roll back, if at all.

To ensure that requested changes are entirely intentional, make sure that you read the affectation and propagation expectations, that you understand them, and confirm this understanding.

PR Rollbacks have lower priority, and the volunteers are unable to control when or if browsers or other parties using the PSL will refresh or update.

• Yes, I understand. I could break my organization's website cookies and cause other issues, and the rollback timing is acceptable. Proceed anyway.

Description of Organization

Reason for PSL Inclusion

MailerLite provides an email marketing and website building platform. We operate two
domains where customers can create websites and landing pages:

mailerpage.io — customers build and host websites as subdomains (e.g. customer.mailerpage.io)
subscribepage.io — customers build and host landing pages as subdomains (e.g. customer.subscribepage.io)
Without PSL, any subdomain can set a cookie scoped to the parent domain (.subscribepage.io / .mailerpage.io), This is a cookie security concern that PSL inclusion directly resolves by treating each customer subdomain as an independent registrable domain.

Both mailerpage.io and subscribepage.io are registered with more than two years remaining, and we commit to maintaining their registration in good standing with more than two year remaining on the term.

Number of THOUSANDS of distinct users this request is being made to serve:

Over 200,000 distinct users (current actual count) — distinct individuals who deploy and operate websites and landing pages on the below domains.

*.subscribepage.io: 263,877
*.mailerpage.io: 4,573
