Share relevant screenshots, i.e., DNS from Mailgun and Cloudflare.


I’m not only one who have the same issue for example
Error sending email! Error sending email: Failed to send email. Reason: Invalid login: 535 Authentication failed. Please check your email settings and resend the invitation.

any solution could you provide me with a simple solution to fix email deliverability because subscribe is very important option to attract views or email list regards

And a screenshot from your Mailgun console. Furthermore, do you have any email accounts associated with guru61.com?

Presently, your DNS is incorrect, but you are providing insufficient information to assist appropriately.

the first one for the main domain, sending newsletter posts works normal but for subdomain it’s not working and show error send majic link any suggestion! if I change the SMTP to direct. users only whom have the hotmail and yahoo can subscribe

Please provide the information requested.

It’s understood that bulk mail uses the API, and transactional uses SMTP. Your issue is related to DNS; you haven’t configured things correctly, e.g., domain and subdomain point to Mailgun servers. However, it’s necessary to see what you have set up in Mailgun for transactional mail, so this may be checked with your Cloudflare entries.

If you can’t post relevant information, I am unable to assist. Similarly, if you don’t show courtesy and confirm when things do work as a result of help given–the original topic–help will be given less freely in future.

Thanks for your feedback, I’m sorry if my replies and comments didn’t satisfy your expectations. I’m very happy with your solution but I don’t have much experience with DNS records. I am following some online instructions

  1. I created a new subdomain like the preview examples :

    as screen show two domain names with right active notification and some sends with the main domain

Delete the MX records for your bare domain in Cloudflare, i.e., guru61.com. You should then have the following:

problems ! still showing send field majic link

I did, show success ! nothing works

Hold on! Your Mailgun SMTP settings work.

Once again you have posted private information on a public website. I’m not going to delete them since it’s already out in the web.

Therefore, you need to immediately change your credentials in the Mailgun interface.

Don’t publish them again!

Now we know SMTP is working, we can revisit your Ghost settings. But first, change your credentials.

Incidentally, I don’t use the live chat feature, so no need to post there.

ok, now what are the next steps to modify the credentials, any option or command or all the work is done

You should stop cutting and pasting commands without reading and understanding what you’re doing.

The result of the test was a success, but you won’t have received an email because you sent it to foo@bar.com!

So try again.

Then make sure your config.production.json file uses the same credentials and settings.

subscribe not working ?why everything seems correct

What doesn’t work? What do you see? Please share relevant information.
