More details
Email is the universal delivery channel for signature requests. Every professional has email; not everyone has Slack, WhatsApp, or a specific app. By delivering the signing link via email, you guarantee the recipient can access it.
What the recipient receives: - A professional email from Signbee with your branding context - A clear 'Review and Sign' call-to-action button - A brief description of the document and who sent it - The signing link (also works if the button doesn't render)
No account required: The recipient doesn't need a Signbee account, doesn't need to download an app, and doesn't need to register. They click the link, verify their email with a one-time code, review the document, and sign.
Email deliverability: Signing request emails are sent from Signbee's authenticated domain with SPF, DKIM, and DMARC configured. This ensures they land in the inbox, not spam.
Customisation: You can customise the email subject line and include a personal message to the recipient via the API parameters.
Frequently asked questions
Does the recipient need an account to sign?
No. They receive an email with a signing link, verify their email with a one-time code, and sign immediately. No account, no app, no registration.
What if the signing email goes to spam?
Signbee emails are sent from an authenticated domain with SPF, DKIM, and DMARC configured. If the recipient can't find the email, check their spam folder. The signing link can also be shared directly.
