Once you reach a subscriber number of 500, you won't be able to send any more notifications to your subscribers. The opt-in, though, would still be active on your website and you can keep collecting more subscribers. After hitting the 500 limit, you'll have to upgrade to one of the paid plans to be able to send notifications to the subscribers you have collected.
You can send unlimited notifications each month on any plan. No limits!
In case you decide to stop using our service at any point in future, needless to say, we'll be sad to see you go. But yes, we will let you keep your subscriber data (provided that you give us your GCM key for Chrome implementation and Certificate details for Safari implementation at the time of setting up your account) and you can export the list easily. Only applicable to paid plans though.
If you are not satisfied with the service, you can email us at firstname.lastname@example.org. We'll cancel your subscription right away.
Please send us an inquiry at email@example.com One of our crew members will be assigned your query and will mostly get back to you in 1 business day.
