64kb echs card compliant e mail id

I think there may be a bit of confusion here!

An "ECHS" card is a type of medical card issued by the Indian government to Ex-Servicemen Contributory Health Scheme (ECHS) beneficiaries. It's not related to email IDs.

If you're looking for an email ID that is compliant with the 64KB limit, I'm afraid that's not a feasible request. Email IDs are not limited by a specific file size, and most email providers don't have a file size limit for sending emails.

However, if you're looking for an email ID that is compliant with the 64KB limit in terms of attachment size, most email providers have a much higher limit than 64KB. For example, Gmail's attachment limit is 25MB, while Outlook's attachment limit is 20MB.

If you could provide more context or clarify what you mean by "64KB echs card compliant e mail id", I'd be happy to help you further!
