Some customers of of the drip marketing suite Arigato PRO can’t run cron jobs on their servers for one or another reason. But this is not reason to worry:
Arigato Pro does not require cron jobs to send scheduled emails. We just recommend setting up cron jobs because this method is more reliable and less resource intensive. If for some reason you can’t set up cron jobs, there are alternatives:
a) Use the option “I will rely on my blog visitors to initiate the email sending”. You’ll find it on the Arigato Pro Settings page:
b) Use some of the many web based cron job services. For example this one is free, and there are many more free or very reasonably priced ones. Do a search for “web cron jobs” and choose a service you like.
Saying all this, please have in mind that cron jobs are not some kind of luxury or high-tech service. They are provided even by the cheapest web hosts. If your hosting service cannot provide such basic feature you should probably consider changing it.
