# From your dashboard, you can generate an API Key if you haven't already

# at https://app.smtp2go.com/settings/apikeys/
|
|
|
|
# The API Key from here which will look something like:
|
|
# api-60F0DD0AB5BA11ABA421F23C91C88EF4
|
|
#
|
|
# Knowing this, you can buid your smtp2go url as follows:
|
|
# smtp2go://{user}@{domain}/{apikey}
|
|
# smtp2go://{user}@{domain}/{apikey}/{email}
|
|
#
|
|
# You can email as many addresses as you want as:
|
|
# smtp2go://{user}@{domain}/{apikey}/{email1}/{email2}/{emailN}
|
|
#
|
|
# The {user}@{domain} effectively assembles the 'from' email address
|
|
# the email will be transmitted from. If no email address is specified
|
|
# then it will also become the 'to' address as well.
