Hi there, Kat4101.

I understand how important it is for your company to edit the estimate email format to look more professional. This option is unavailable in QuickBooks Online (QBO). We see consumer feedback as an opportunity to improve the numerous features of our products. I'd recommend giving our engineers direct feedback. They may look into this suggestion and incorporate it into future updates. Let me demonstrate:

1. Go to the Gear icon.
2. Hit Feedback.
3. Type in your recommendation in the Share your feedback field.
4. Click Next.
5. Follow the on-screen instructions to complete the process.

I've attached screenshots below for your reference:

You'll want to include a summary in the email, instead of the full details. Here's how:

1. Click the Gear icon.
2. Select Account and settings and proceed to the Sales tab.
3. Go to the Online delivery section and select Edit.
4. Choose Show short summary in email.
5. Click Save and Done.
