How to Send Account Deactivation Emails with NestJS
Learn how to send account deactivation emails from your NestJS application using AISend's AI-powered email API. This guide covers setup, implementation, and best practices for confirming account deletion or suspension.
What are account deactivation emails?
Account Deactivation emails are transactional emails triggered by user actions, specifically for confirming account deletion or suspension. These emails are critical to your application's user experience — if a account deactivation email doesn't arrive, users lose trust in your product. Account Deactivation emails typically have high open rates (60-80%) because recipients are expecting them. This makes deliverability especially important — you need an email API that ensures these messages reach the inbox, not the spam folder. AISend's AI-powered routing selects the best email provider for each recipient, maximizing inbox placement for your account deactivation emails.
Setting up AISend with NestJS
Start by creating a free AISend account at aisend.app — no credit card required. From your dashboard, create an API key. Install the AISend Node.js SDK: npm install aisend. The SDK provides TypeScript types and handles retries automatically. For production use, store your API key in environment variables — never hard-code credentials in your source code.
Sending account deactivation emails
To send a account deactivation email, make a POST request to the AISend API with four fields: from (your verified sending domain), to (the recipient's email), subject (a clear, descriptive subject line for your account deactivation email), and html (the email body). For account deactivation emails specifically, keep the content focused and actionable — include only the information the user needs for confirming account deletion or suspension. Avoid promotional content in transactional emails as it can hurt deliverability and may violate anti-spam regulations. AISend's AI automatically scores your content for deliverability before sending.
Best practices for account deactivation emails in NestJS
Send account deactivation emails immediately when triggered — delays frustrate users, especially for time-sensitive emails like account deactivation. Use a background job queue to avoid blocking your application's response time. Include clear branding so users recognize your email. Keep subject lines descriptive and specific (e.g., "Your account deactivation from [AppName]"). Set up webhook handlers to track delivery status and handle bounces. Always include both HTML and plain text versions for accessibility. Use AISend's domain verification to set up SPF, DKIM, and DMARC for maximum deliverability.
