IOT Server recommendations.

I have just discovered the IOT server I have been using for the last year+ or so has just shutdown.

Does anyone out there have any suggestions for a service that records simple temperature data sent to the cloud,.. with some sort of alarm function that sends an email and or SMS message,.. and ideally for free,.. but appreciate that will probably come with upload limits...
I have seen the thingspeak web site,.. which would work,.. but the MATLAB licence which I understand does the alarm type checking costs £100+ per year.
Anyone tried the Amazon service,.. this seems to offer a service based on time... but the web page is not too clear on how it all works...
Many Tx for any feedback
