Disify vs Sendinblue
Disify
A free, keyless REST API that checks an email's syntax, DNS/MX records, whether its domain is disposable or on an allow-list, and whether its mailbox is a role address, returning a single JSON verdict. No signup is required for the core lookup, with paid business accounts available for higher volume.
Sendinblue
Sendinblue rebranded to Brevo in 2023, and its REST API still covers the same ground under the new name: transactional and marketing email, SMS, and contact/campaign management behind an API-key header. A free plan covers a daily email allowance before metered and subscription paid tiers.
