If you send your email "direct" is must still pass through processing
stages at your ISP. At the very least, it will pass through their
routers and gateways, any one of which can interfere in various ways
with the connection. As an example, some ISPs will block outgoing smtp
connections unless they originate in their own email servers as a way
to fight spam relays. Realistically, an ISP is not going to trawl
through every connection to extract detailed info about it - the
[amount of data | £cost] is just unmanagable.
If you are in the UK, then the law provides for your ISP to be forced to
hold your data, but that would only be practical in cases where a
person was already under physical surveillance and monitoring - again,
the quantity of data is prohibitive for it to be used for blanket
monitoring. On the other hand, an individual who serves his own mail
may fall foul of the act if they cannot produce logs on request.

If you mean that Freeparking sets your MX record to point at your local
mail server, then it bypasses your ISP to the extent that your incoming
mail does not get collected on their servers, but passes through their
routers and gateways on its way to you.
If you mean that Freeparking receives your mail and you collect it from
them then you have only shifted the issue to a different company.

If you mean that Freeparking sets your MX record to point at your local
mail server, then it bypasses your ISP to the extent that your incoming
mail does not get collected on their servers, but passes through their
