What is an email sending service (paid) that does NOT require authentication by changing the DNS records of the domain?

Question

Hi, I am interested in knowing an email services where is NOT needed to authenticate the domain by changing the DNS records.

In Mailchimp you need you need to modifying the domain's DNS records.

With sendgrid, it is the same case, (they call it white labelling)

With mailgun it is the same.

Do you guys know a service (paid) where it is possible to send emails without having to alter the domain's DNS records?

Answer 1

The question does not really make sense. These DNS records normally have a notional ownership of the email service, and as such it is up to the service to decide whether they are going to require authentication or not.



I suspect that paid for services that do not validate the sender will become increasingly rare. These services will always prefer to protect their reputation by minimising the possibility of their servers being used for phishing or spam.



Why do you want to send unauthenticated emails or emails that have false trails? You might be able to update your own cached copy of a DNS record, however, the receiving server can check the sending IP address with the domain name from the sending email address. This is likely to be from a different DNS tree and so will not include your updated record. The problem with trying to fool around with DNS records is that they will not be the definitive record and when the cached copy expires the changes will be lost.



If you are trying to send emails through a single email service using sending addresses from other services, most services allow you to register alternative email addresses but they ask you to validate that you have access to the alternative email address.



I hope this helps.

WHY? If it is YOUR domain changing the records (MX - mail exchange) for the mail server is not a big deal. To have that email server send mail it has to have an MX record for the domain that is sending the mail, that will need a DNS change! IF you don't want to change the domains DNS you have to use the actual domain that is sending the mail... gmail, hotmail, etc. Did you know even gmail can be used for your domain... but you HAVE to change the MX records to the gmail system or gmail is the domain name used. Yes gmail charges for that use!

Just study up a bit on how mail services work! Changing the records for the mail service is not hard and is the proper way to send mail!

This is probably adding a DKIM record. Sending things without this is going to reach fewer and fewer accounts as DKIM is implemented on the receiving end. It isn't the sending side requiring it. So by insisting on not having it just means you are settling for a more broken service, more bounces.
