SadaSend vs SendGrid: Why modern developers are ditching Twilio SendGrid in 2026

import { SadaSend } from 'sadasend';

// Synchronous, edge-validated transactional delivery
const client = new SadaSend(process.env.SADASEND_API_KEY!);

export async function sendAuthToken(userEmail: string, token: string) {
  // SadaSend validates DNS signatures and suppressions BEFORE returning
  const response = await client.emails.send({
    from: 'auth@yourdomain.com',
    to: userEmail,
    subject: 'Confirm Your Email Address',
    html: `<p>Your login token is: <strong>${token}</strong></p>`,
    tags: ['authentication']
  });

  // Zero delayed bounce surprises: immediate message confirmation
  console.log('Status: delivered | Message ID:', response.id);
  return response;
}
