Email Providers — TrueGrade Docs

TrueGrade sends transactional emails for compliance alerts, subcontractor invitations, report digests, and team notifications. By default, TrueGrade uses a shared sending infrastructure. Organizations on Business and Enterprise plans can configure their own email provider for better deliverability and custom sending domains.

Supported Providers

Provider	Notes
Resend	Modern API-first provider, excellent deliverability
SMTP	Any SMTP server (SendGrid, Mailchimp Transactional, self-hosted)
Postmark	Focused on transactional email, high deliverability
Mailgun	High volume transactional and marketing email
Amazon SES	Cost-effective for AWS-native organizations

Resend

Create a Resend account and add your sending domain at resend.com
Verify your domain by adding DNS records
Generate an API key under API Keys
In TrueGrade: Administration → Integrations → Email → Resend
Enter your API key and your verified sending domain
Set the From name (e.g., “TrueGrade Notifications”) and From email (e.g., notifications@yourdomain.com)
Click Send test email to verify delivery

SMTP

Provide the following SMTP credentials from your provider:

Field	Example
SMTP host	`smtp.sendgrid.net`
Port	`587` (TLS) or `465` (SSL)
Username	Your SMTP username
Password	Your SMTP password or API key
From name	`TrueGrade Notifications`
From email	`notifications@yourdomain.com`
Encryption	TLS / SSL / None

In TrueGrade: Administration → Integrations → Email → SMTP. Enter the credentials above.

Amazon SES

Verify your sending domain in the AWS SES console (under Verified Identities)
Create an IAM user with ses:SendEmail and ses:SendRawEmail permissions
Generate access credentials (Access Key ID and Secret)
In TrueGrade: Administration → Integrations → Email → Amazon SES
Enter your AWS region, Access Key ID, Secret, and verified From email

If no custom email provider is configured, TrueGrade uses its default shared sending infrastructure. Emails sent from the shared infrastructure use a @mail.truegrade.build return path. Configuring your own provider with your domain significantly improves deliverability and trust with subcontractors.

Testing Email Delivery

After configuration, send a test email from Administration → Integrations → Email → [Provider] → Send Test. Check the inbox for the recipient email you enter. If the test email is not received, check:
