I can't use a Yahoo, Laposte, Protonmail or Zohomail address to send my emails

In this article, you will learn why you cannot use Yahoo, Laposte, Protonmail, or Zohomail addresses to send your emails.


Yahoo does not allow sending emails from servers other than their own (they use an email authentication mechanism called DMARC).

Therefore, if you try to send emails from systeme.io or any other software with your Yahoo address, your emails will be rejected by the receiving mail servers and will not reach their destination.


Laposte protects its domain with DMARC, so messages sent from an email address with this domain will be blocked due to DMARC errors.

Zoho (Zohomail) 

The DMARC rejection policy is also active on Zoho's domain, making it impossible to send emails with an email address from this domain. 


Protonmail has a quarantine policy for emails sent with its domain outside its servers, so the emails sent are received as junk mail (spam folder).

Recommended solutions :

1) We recommend that you register your domain name with a mailbox host of your choice, it only costs a few dollars per year (click here to check prices).

2) Use one of the email addresses below which can be used to send emails through systeme.io :

  • Gmail
  • Microsoft (Outlook, Msn, Hotmail, Live)
  • Orange
  • SFR

It should be noted, however, that these are not professional email addresses, and receiving servers have a tendency to reject emails from these domains. To avoid any problems in sending emails to your recipients, the best option is to purchase domain name and mailbox host as recommended above.
