For what it's worth, I very rarely give out my actual phone number on electronic forms, and my email address does not contain an obvious person's name. The number 0123456789 usually is accepted by software as your phone number.
If a delivery company need to contact me they will email me. Nothing is so urgent that they need my actual number – if they can't deliver, they will have to come back another day, that's their job.
Too many times, after I have given my email address to a company or supplier for work related reasons, I get a lot of unsolicited spam. And these are companies who supposedly adhere to the GDPR rules, but clearly their systems are unprotected or riddled with viruses, allowing hackers to trawl their contact lists.
Regarding emails, they are best thought of as an electronic postcard. Any body who handles them can read them. So don't send personal details, photos or data over unencrypted email. One such GDPR company, (above), sent my bank account details back to me in an unencrypted email………..Another, sent my full home address, and this was after I had told them I didn't want to give out my email address but they insisted. A doctor really had a problem understanding why I did not want personal medical data sent over email.
So be very careful with your data, especially anything relating to your identity. Many people and companies who should know better, are very cavalier with sensitive data in emails. Some are just lazy and cannot be bothered sending things via the Royal Mail. Apple iMessage is encrypted, and I believe What'sApp is too, although I do not use the latter.
