Android Question Problem to Send GPS Position by email

Hello, Im trying to send by email a link to google maps with the lantitude and longitude using Net library:

SMTP.Body = $"http://maps.google.com/maps?q=${latitude},${longitude}"$

When I receive email in:

Hotmail:
http://maps.google.com/maps?q=8.01220054968499,-57.58156790640374

gmail:
http://maps.google.com/maps?q-38.01220054968499,-57.58156790640374

and should be:

http://maps.google.com/maps?q=-38.01220054968499,-57.58156790640374

What I can do? Thanks in advance
