The record

Email validation: Email list cleaning combines hygiene scans with real-time email verification to identify threats including spam traps, hard bounces, complainers, and bots.
Other services: The site lists phone validation, email activity, data enrichment, and postal validation among its products.
Email activity: Email Activity matches web and email engagement from the last 30, 60, or 90 days.
Data enrichment: Data enrichment can use email addresses to append fields such as name, postal address, age, gender, and ethnicity.
Postal coverage: Postal validation standardizes and checks US and Canadian residential and commercial addresses through bulk upload or API.
Phone coverage: Phone validation identifies US phone numbers and reports details such as line type, carrier, and complaint or blacklist status.
API: The API uses REST over HTTPS with GET or POST methods, and server IPs or client URLs must be whitelisted for access.
File processing: The email validation page says the application and programmatic solutions can process 2 million records in a 24-hour period.
FTP/SFTP: Email validation features include automated FTP and SFTP solutions for list validation.
Security: The company says portals use TLS 1.2, sensitive databases use Transparent Data Encryption, and sensitive files use AES encryption.
Compliance: The homepage says EmailOversight is CCPA and GDPR compliant and offers EU-based API endpoints to EU customers by request.
Support: Pricing pages advertise 24/7 customer support, and the site lists [email protected] and 1 (213) 325-3100.
Trial: The FAQ says signup allocates 200 free validation credits and the trial ends when those credits are used.
Usage limit: The FAQ says there is no limit on the number of emails in a single list, though larger files take longer to clean.
