Email Settings & Deliverability

To ensure your emails reach the inbox and not the spam folder, Donutwork provides advanced tools for mail server configuration and domain authentication.

SMTP Configuration

Donutwork allows you to choose between two sending modes:

1. System SMTP: Use Donutwork’s default infrastructure for immediate setup.
2. Custom SMTP: Configure your own providers (e.g., SendGrid, Mailgun, Amazon SES) by entering Host, Port, Username, and Password.

Domain Authentication (SPF & DKIM)

Security is key to email delivery. Use the following settings to authorize Donutwork to send mail on your behalf.

SPF Record

Add this value to your domain's SPF record in your DNS settings: include:_spf_hosted.donutwork.com

Enforce DKIM

DKIM adds a digital signature to your emails. To enable it:

1. Toggle the Enforce DKIM option in settings.
2. Add a CNAME record to your DNS:
   • Host: donutwork._domainkey.YOUR_DOMAIN
   • Target: smtp._domainkey.donutwork.com

Alternative Senders

You are not limited to a single "From" address. You can define multiple senders for different purposes:

• support@yourbrand.com for help desk replies.
• billing@yourbrand.com for automated invoices.
• news@yourbrand.com for marketing updates.

Each sender can have a unique Display Name to increase user trust.
