Yep, this is unbearable unfortunately. I'm only on a free plan but how can I get into a business plan or higher if basics like these fail?

Not supporting 2048 DKIM keys is a real problem today

mail-tester.com; dkim=fail reason="signature verification failed" (1024-bit key; unprotected)

Not supporting 2048 DKIM keys is a real problem today.
This is particularly true of Microsoft hotmail addresses and other mail providers.
We have a large percentage (6%) of our mail that doesn't go through because it's "softbounced".
You have to do something and upgrade your platform, because our customers are really unhappy about not receiving their mail.
We can't tell them it's their fault for choosing hotmail as their provider, clearly the problem is on your side.
You need to comply with market standards, especially when it comes to security.
Thank you

Any update on this? It's critical for our customers.

This is a critical enhancement for our customers

Agree that 2048 bit DKIM keys is something that should be considered. We see the configuration getting flagged by security tools.

We really need an update on this.

We need 2048 support or will have to change back to SendGrid as our mail provider. (I.e. SendGrid already supports 2048)

2048 bit encryption key is now required by more than 2 of our clients. Is this feature coming soon?

Yup - my mails are now not reaching our customers anymore. Please

Thank you Mailjet for your feedback on this minor issue !

You are right to market your product on your homepage with the catchline "Unmatched deliverability"

We are experiencing the same issue with our deliver-ability on our mail. The reduced key length pulls down the rating quite significantly.

I'm not sure why this would be a feature request and not just a follow the standard requirement.

our mails no longer reach our customers because they are marked as spam due to the outdated dkim key strength. We'll have to look for another provider if the problem isn't fixed soon.

Any Update on this

I need to enhance the sender reputation of emails for business transactions and it does seem with mail-tester and other platforms for testing email deliverability that 1024 key length needs to be upgraded to 2048 to pass testing. Not sure if this does enhance deliverability but if more than one testing platform suggests the DMARC/DKIM testing is failing then perhaps we need to consider this?

Please consider using a stronger key. Security platforms are penalising your customers due to us using your current key.

Up,
Can we have an answer and an estimation date for implementation of the 2048 bit key?

DKIM 2048 keys are a standard in 2022.

Any news?
This is a deal breaker.

Same as below:
Error message: "dkim=fail reason="signature verification failed" (1024-bit key; unprotected)"

Any news? No feedback from mailjet Team?

This is an issue for us as well. Please switch DKIM to 2048-bit keys.
