Email notification optimization

As too many emails sending out from EasyCron has resulted in some problems, we has reduced the amount of email notices by changing the email notice triggering mechanism.

The main problems caused by frequently emailing are:

1) Many email service providers deem us as SPAM sender, block our emails (or/and IPs) constantly. This has brought big trouble to EasyCron and our users. For example, many expired users could not receive expiry email notices and didn't renew their accounts on time; some crucial cron jobs failed but didn't receive attention, and so on.

2) Some users' email box were filled up by emails sent by us.

3) The credit and authority of our domain and IPs descends as black listing done by other parties.

4) Our email server keeps being hit by huge amount of bounced emails from recipients.

Now EasyCron sends out email notices only when:

1) starts failing, or

2) returns to success from failure.

That is to say, if your cron job fails consecutively for more than one time, only one failure email notice will be sent to you.

You could also specify a "sensitivity" setting to configure only after how many consecutive failures that the failure notice will get sent.

Email notification and failure threshold

If in some cases, you really need to be notified for each failure or execution of your cron job, you could utilize the "webhook" feature.
