Signatures appear at the bottom of AI-generated emails so recipients see your name, title, and contact details. ## Before you start * A Nudgen account * Owner, admin, or member access ## Create a signature 1. Go to **Settings** → **Signatures**. 2. Click **New signature** or **Add signature**. 3. Enter a **name** (e.g. "Default", "Sales", "Support") so you can identify it when selecting. 4. Add your signature content. You can use: * Plain text * Basic formatting (bold, links, line breaks) * HTML if supported 5. Save. ## Use a signature in campaigns When creating or editing a campaign, choose which signature to attach. The signature is appended to the email body when the campaign is sent. You can have multiple signatures and pick the right one per campaign (e.g. sales vs support). ## Edit or delete * **Edit:** Open the signature, change the content or name, save. * **Delete:** Remove the signature. Campaigns that already used it keep the content that was sent; future campaigns will need a different signature selected. If you delete a signature that's still selected in a draft campaign, you'll need to pick another signature before sending. ## Content expectations and safety * Keep signatures concise. Long signatures can trigger spam filters or look unprofessional. * Avoid large images or complex layouts. Simple text with a link or two works best. * Include your name, title, and contact method (email or link). Optional: company name, logo. * Signatures are sanitized before being appended to emails to prevent injection. Only safe HTML and links are allowed; risky content is stripped. ## What happens next * [Create a campaign](/en/campaigns/create) and select your signature before sending. * Create multiple signatures for different teams or use cases. ## Troubleshooting Ensure you selected the signature when creating or editing the campaign. Check the preview before sending. Stick to simple formatting. Complex HTML may not render consistently across email clients. ## Related docs Attach a signature when creating a campaign.
