When it comes to invoicing, email remains a popular and effective method for delivering bills to clients. However, simply sending an invoice via email isn't enough. To ensure your invoices are received, processed, and paid promptly, while also optimizing for Google SEO, here are 18 email best practices to follow:

1. Clear and Concise Subject Line

Craft a subject line that clearly states the purpose of the email, such as "Invoice for [Service/Product] - [Your Company Name]." This helps the recipient understand the email's content immediately.

2. Use a Professional Email Address

Send invoices from a professional email address linked to your domain, not a generic or personal email account. This adds credibility to your business.

3. Invoice as PDF

Attach the invoice as a PDF. PDFs are universally readable and maintain the invoice's formatting.

4. Invoice Details in the Body

Summarize the invoice details in the email body, including the invoice number, date, total amount, and payment deadline.

5. Personalized Greeting

Start the email with a personalized greeting, addressing the recipient by name. This adds a personal touch and grabs their attention.

6. Thank the Client

Express gratitude for the client's business. A simple "Thank you for your business" goes a long way in building good client relations.

7. Payment Instructions

Provide clear payment instructions, including accepted payment methods, and any relevant bank account or online payment details.

8. Contact Information

Include your contact information in case the client has any questions or needs further assistance.

9. Due Date Reminder

Highlight the payment due date and any late payment policies you have in place.

10. Itemized List of Services/Products

If possible, include an itemized list of services or products in the email body or as an attachment. This provides transparency and reduces confusion.

11. Use Plain Text

Avoid using fancy HTML templates or excessive formatting in the email body. Plain text emails are more likely to be read correctly by various email clients.

12. Avoid Spam Triggers

Refrain from using words or phrases that might trigger spam filters, such as "free," "win," or "prize."

13. Test Email Deliverability

Periodically test your invoice emails to ensure they're not being marked as spam or caught in filters.

15. Follow-Up Email

Consider sending a follow-up email a few days before the payment deadline as a friendly reminder.

If you provide a link for online payments, ensure it's secure (HTTPS) and trustworthy.

17. Privacy Policy Link

Include a link to your privacy policy to assure clients that their personal information is protected.
