It is always free to reply or send a message to a paid user who has a license. You will not be deducted a credit, and if you have no credits you will still be able to send to a paid Switch user.
If you have received a Switch Secure Email, it is likely that they will be paying subscribers.
Credits are used when free users are sending to recipients who are not Switch customers. One credit is used each time a free user accesses a message from another free or PAYG user. Credits can be used in the following ways:
- Sharing 1 Switch package with 1 recipient uses 1 Switch credit
- Sharing 1 Switch package with 5 recipients uses 5 Switch credits
- Sharing 5 Switch packages with 1 recipient uses 5 Switch credits
Every free account starts off with 25 credits they can use if they wish.
Although you cannot purchase additional credits, it is possible to purchase a subscription allowing you unlimited use of Egress Switch. Sign into the Switch Administration Panel and click on 'Purchase Switch' to do so.
