How To Send Email Invoices?

You have your email templates ready, but how do you send them? Here is the step-by-step guide so that you don’t miss any important details while sending invoice emails.

1. Use a good email automation tool

Start by choosing an email automation tool designed to help streamline and automate your email sending process.

The best tool will let you create your invoice email template and save it for later use. This will help you save time and effort every time you need to send multiple outstanding invoices to your clients.

If you are looking for an affordably priced email automation software, don’t forget to check out EngageBay. Ideal for small businesses and freelancers, it provides a wide range of features that can amp up your email marketing game.

2. Include a standardized email subject line

Hence, make sure to add a standardized subject line before hitting the ‘Send’ button. The subject line should be short and clearly convey what the email is about.

3. Add the template to the body of your email

To help save time, you should add the template you want to use to the body of your email.

Simply go to the email application you use and create a standard email template that you can use later. When you need to send an email, simply click on the template, customize it if need be, and click ‘Send.’

5. Attach the invoice to your email

Since the invoice contains all the details regarding the payment, don’t forget to attach a copy before sending the email to your clients.

6. Proofread your email before sending

Before you hit ‘Send,’ ensure that you have proofread your email.

The email should be free from any grammatical errors, have the invoice attached, and contain accurate information about the amount due, the projects worked on, due dates, and other information about you or the client.

7. Schedule a time to send the emails

You can either choose to email the invoice immediately or at another time.
