Migration Guide

Switch from SendGrid, Postmark, or Resend to Wraps. Side-by-side code comparisons, cost analysis, and step-by-step migration instructions.

Why Migrate to Wraps?

Own your infrastructure
Email infrastructure deploys to your AWS account. No middleman, no vendor lock-in.
$0.10 per 1,000 emails
Pay AWS directly at transparent pricing. No markup, no surprise bills.
No vendor lock-in
Infrastructure stays in your account even if you stop using Wraps. Your data is always yours.
Full data ownership
Email logs, metrics, and sending data live in your AWS account with full data residency control.

Migrating from SendGrid

Replace your SendGrid API key with OIDC-based authentication. No more managing API keys in environment variables.

SendGrid (before)

import sgMail from '@sendgrid/mail';sgMail.setApiKey(process.env.SENDGRID_API_KEY);await sgMail.send({  to: 'user@example.com',  from: 'hello@yourapp.com',  subject: 'Welcome!',  html: '<h1>Hello!</h1>',});

No more API keys

Wraps uses OIDC for authentication when deployed on Vercel, or IAM roles on AWS. No secrets to rotate or leak.

Migrating from Postmark

Postmark uses different field names (PascalCase). Wraps uses a familiar camelCase API that matches modern JavaScript conventions.

Postmark (before)

import { ServerClient } from 'postmark';const client = new ServerClient(process.env.POSTMARK_SERVER_TOKEN);await client.sendEmail({  To: 'user@example.com',  From: 'hello@yourapp.com',  Subject: 'Welcome!',  HtmlBody: '<h1>Hello!</h1>',});

Migrating from Resend

Resend and Wraps have a similar developer experience, but with Wraps the infrastructure lives in your AWS account at a fraction of the cost.

Resend (before)

import { Resend } from 'resend';const resend = new Resend(process.env.RESEND_API_KEY);await resend.emails.send({  to: 'user@example.com',  from: 'hello@yourapp.com',  subject: 'Welcome!',  html: '<h1>Hello!</h1>',});

Same great DX, you own the infra

The API is intentionally familiar. The difference is that your emails flow through infrastructure you own in your AWS account.

Common Migration Steps

1
Deploy infrastructure
terminal.sh
npx @wraps.dev/cli email init

Add your domain

terminal.sh

npx @wraps.dev/cli email domains add -d yourdomain.com

3
Install the SDK
terminal.sh
npm install @wraps.dev/email
4
Update your send calls
Swap your existing import and client initialization with the Wraps SDK as shown in the examples above.
5
Verify DNS (DKIM, SPF, DMARC)
Configure your DNS records for email authentication. See the domain verification guide for details.
6
Test and cutover
Send a test email, verify delivery, then switch your production traffic to Wraps.

Cost Comparison

Monthly cost by email volume. Wraps uses AWS SES pricing at $0.10 per 1,000 emails with no markup.

Monthly Volume	SendGrid	Postmark	Resend	Wraps
10,000	$19.95	$15	$20	$1
50,000	$19.95	$50	$20	$5
100,000	$34.95	$100	$80	$10
500,000	$249.95	$500	$380	$50
