when a new subscriber signs up, a good idea i think is to, set the customer expectations of the service you are providing, by telling the customer;

- the first and last issue of their subscription, when to renew their subscription.

- what date (or approx) the first issue they will receive.

- what regular dates (approx) the customer can expect their digital magazine to emailed to them.

This would be useful information to tell new subscribers and would set the customer expectations.

By doing this, one benefit, for example, is if for some reason a customer does not receive their magazine by due date, this problem could be resolved before the subscriber misses a copy, rather than the customer missing a copy, then resolving the problem with you, if the problem is a technical problem, lets say which is out of your control, you are most likely to loose this customer ...

Reactive (after the problem has occurred) customer support is the last option, not the first ...

Proactive customer support tends to garner brand loyalty ...

I look forward to receiving my first subscription,
