+# Ensure you've added a Senders Domain and have generated yourself an
+# API Key at:
+#   https://app.sparkpost.com/dashboard
+
+# Note: For SMTP Access, your API key must have at least been granted the
+#   'Send via SMTP' privileges.
+
+# From here you can click on the domain you're interested in. You can acquire
+# the API Key from here which will look something like:
+#    1e1d479fcf1a87527e9411e083c700689fa1acdc
+#
+# Knowing this, you can buid your sparkpost url as follows:
+#  sparkpost://{user}@{domain}/{apikey}
+#  sparkpost://{user}@{domain}/{apikey}/{email}
+#
+# You can email as many addresses as you want as:
+#  sparkpost://{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.
+#
+#  The {domain} must cross reference a domain you've set up with Spark Post
+#
