Intermittent issues with mails not sending, and even disappearing completely.

Intermittent issues with mails not sending, and even disappearing completely.

A few weeks ago a notification appeared in my Zoho Mail App on Samsung smartphone saying "You have unsent mail in the Outbox".

I assumed a recent email had not sent, to my horror when I looked at the unsent messages there were important mails from *months* ago that had not sent - and yet this was the first time I had seen the message pop up.

Since then I have noticed that I have to check my unsent messages frequently because I often now have mails that won't send.

This may or may not be connected, but I also experienced a serious issue where I sent an email via the browser and everything seemed fine - except when I went to look for the email in sent items it wasn't there. It had completely disappeared.

A few days later I sent another email, and my wife was sitting with me when I sent it. Again, it completely disappeared. it didn't send, it didn't report an error, it was like it had never existed.

I am seriously considering whether I need to move from Zoho as I am concerned about having to check and double check the sending of important emails.

Is anyone else experiencing these issues?

Thanks.
