Sendzovo is a transactional email platform for developers that combines email sending and email verification in one service. Send password resets, sign-in codes, receipts and account notifications through a REST API or standard SMTP, with code examples for cURL, PHP, Node.js, Python and C# and an official PHP SDK.
Recipient verification is built in: Sendzovo can verify each address before a message is sent, checking syntax, domain and MX records, the mailbox on the receiving server, and risk signals such as catch-all domains, disposable inboxes and role-based addresses. Known-bad recipients are skipped instead of bouncing, and hard bounces and spam complaints are suppressed automatically to protect your sender reputation.
Sendzovo also includes Message Streams to separate transactional and broadcast email, reusable templates and layouts, delivery tracking for bounces and complaints, webhooks, domain-scoped API keys and DKIM, SPF and DMARC setup guidance. A free plan is available.
