Email API for Api Gateway
How api gateway companies use AISend to send reliable, AI-optimized transactional emails.
Why api gateway needs a reliable email API
Api Gateway companies depend on transactional emails for critical user communications — account verification, password resets, order confirmations, billing notifications, and status updates. When these emails don't arrive, users lose trust and revenue is impacted. A failed password reset means a locked-out user. A missing invoice means delayed payment. For api gateway businesses, email deliverability isn't just a technical metric — it directly affects customer satisfaction and bottom-line revenue. AISend provides the reliability and deliverability that api gateway applications require.
Key email types for api gateway
Every api gateway application needs to send several categories of transactional emails: authentication emails (verification, password resets, 2FA codes), notification emails (activity updates, alerts, reminders), billing emails (invoices, receipts, payment failures), and lifecycle emails (welcome sequences, onboarding guides, feedback requests). Each type has different deliverability requirements and timing expectations. AISend's AI handles this automatically — routing time-critical emails like 2FA codes through the fastest provider, while optimizing less urgent emails for maximum inbox placement.
