SendWith

Send critical emails to your users that don't end up in spam

Simple Setup: No complex APIs or DNS settings. Sign in with your existing email provider (Gmail & Google Workspace supported, more coming soon!) and use the SendWith API immediately.

Boost Deliverability: Leverage your existing email provider's trusted reputation to ensure emails land in inboxes, not spam folders. Perfect for sending critical emails like magic links or account updates.

Seamless Tracking: View all your automated emails alongside regular messages in your sent folder. Replies come right back to your inbox for easy management.

1. Install the integration and authenticate your email service provider

Install the integration using the "Add Integration" button at the top of this page. During installation, we will create a SendWith account for you, which is separate from your Vercel account. During the installation process, you'll be prompted to authenticate your email service provider (such as Gmail or Google Workspace). This allows SendWith to send emails on your behalf.

2. Send an email with the API

After installing the integration, you can view your API key and sample code in the SendWith Dashboard. The API key is automatically added to your Vercel project environment variables.
