In subscribers' mailboxes, your newsletter competes with those of all other senders, not just your competition. Therefore, it is crucial to think about the timing of your newsletter.
When does the market send out its newsletters? Is the time of sending bound to fixed days of the week? How often does the competition send out their newsletters?
And when do I plan to send out my newsletter myself?
Admon supports you here with time reporting, analyses of the total mailing and benchmarking.
