Frequently asked questions

Does Pacomail send real emails?

Pacomail is a testing tool and is not intended to send emails to real addresses. However you can send your test emails to a real mailbox (Gmail, Outlook etc.) for testing purposes.

Can I invite collaborators only on one mailbox?

Absolutely! You can manage your team either on an organization-wide scale, in which case they will have access to all your projects and the corresponding mailboxes, or on a single mailbox only. These guests will always be invited as members and will only have access to the mailbox they were invited to.

Can I send a test email to Pacomail from my Gmail?

No, Pacomail is an environment to test sending mail from an external application, it is not a real email client. The mailbox you use is only connected to your application, it does not receive any external email.

What is the best pricing plan for me?

The free plan is best for a person without a team or for a small business that would like to test Pacomail before switching to a more adapted plan.

The business plan is interesting for large companies or organizations that send or test a very large amount of emails.

Can I stop my subscription when I want?

Yes, you can cancel your plan in your payment settings at any time. If your subscription is terminated before the end of the subscription period, you will receive a prorated refund.

I am a public institution or service, can I pay by bank transfer?

Yes, absolutely! We know that billing processes can be complicated as a public service, contact us at and we’ll manage the invoice/order form ping pong together.
