Email tips

📧

Extra blank lines in email copy render inconsistently across clients. Gmail, Outlook, and Apple Mail all handle multiple paragraph breaks differently.

💡

Enable "collapse multiple blank lines" to reduce any triple or quadruple spacing to a single paragraph break — consistent across all email clients.

📝

Subject lines and preheader text must have no leading/trailing spaces. Email platforms sometimes count these against character limits.

✉️

Copying transactional email templates from a design tool often introduces extra whitespace. Clean before pasting into your ESP (SendGrid, Postmark, etc.).
