Emails to E-on next returned undelivered

dogfonos

Anyone else had the same problem?

Four times over the past 2 or 3 months I've emailed E-on next yet all emails were returned undelivered with the message:

The user or domain that you are sending to (or from) has a policy that
550-5.7.1 prohibited the mail that you sent. Please contact your domain
550-5.7.1 administrator for further details.

I used these two email addresses: <hi@eonnext.com> and <unhappy@eonnext.com> (currently available on the e-on next website).

I rarely have this 'returned undelivered' issue. Any ideas? Looks like I'll have to try their 'phone contact option - when I have half a day spare.

Where are you sending the emails from?

Do you have an alternative email service you could try - not a different address for EON, but eg. an Outlook account you could send from instead of a Gmail one?

Are you sending from Apple mail or .me domain? Many organisations block these are sources of spam

Are you attaching any large files to the email(s) ?

I send emails from my web-based GMX account. I have a PC-based (client) Thunderbird account which I've linked to my GMX account so I can "fetch" and "store" emails I've sent and received using GMX. I do this just in case GMX pull the plug on me and I lose access - not unknown with web-based email accounts, evidently.

No reason I can't try sending an email through Thunderbird though - thanks for the suggestion.

I too receive emails from hi@eonnext. I guess that shows it's a live email address.

No attachments at all. Also no personal info, no bank details etc. were included in my email text. And the emails were just a couple of lines of text so shouldn't have been a large file.

I think my approach now will be to: (1) Try using Thunderbird email. (2) Leave poor review on Trustpilot (I notice some companies "reach out" to customers who leave negative reviews). (3) 'Phone. (4) Switch energy supplier!
