If you are a pro/enterprise user, you have access to multiple different ways to send emails from Invoice Ninja. We offer OAuth integrations with both Google and Microsoft allowing you to send emails from your own email address.
Connecting either Gmail or Microsoft involves the same steps. Below is a short video showing the steps.
Once you have connected your OAuth account, you can select either Gmail or Microsoft as the Email Provider in
Settings / Email Settings
After selecting the email provider, you'll then want to select the user who has been authenticated to send emails from the field beneath this.
If you prefer to send bulk emails via PostMark, then this is also supported. We do not throttle the outbound emails using Postmark, so this is suitable if you require a high throughput email service.

Settings / Email Settings
If you prefer to send bulk emails via Mailgun, then this is also supported. We do not throttle the outbound emails using Mailgun, so this is suitable if you require a high throughput email service.
Ensure to fill in both your Mailgun Secret and Domain that has been configured.
Email delivery is hard the large email providers such as GMail, Yahoo, Microsoft are continuing their fight against unsolicited / spam emails from filling the inboxes that they serve.
In 2024 it will become even harder with additional checks in place on all emails to ensure that only high quality emails arrive to a users inbox.
In particular, their focus is on working unsubscribe links within emails. Previously we have not needed to insert an unsubscribe link into an invoice email, however now it will become a standard part of all outbound emails to include a unsubscribe link.
If your client clicks on an unsubscribe link, they'll be taken to a page where they can opt out of receiving emails from you. This will mark their client record as "DO NOT SEND" and you will also receive a follow up email advising that this action has been taken by your client.
