I have a basic web hosting account in bigrock.in, and with that come email accounts with ready SMTP access, and through some clicks in their cpanel the email accounts become "verified", don't go into spam so easily. So, using the SMTP credentials from there, I have this api call in fastapi ready to send emails. Sharing python3.8 basic code that I've arrived at after multiple rounds of trial & error. Note that the SMTP credentials are in the # as per https://docs.python.org/3/library/email.examples.html
import smtplib
from email.message import EmailMessage
from email.headerregistry import Address
from email.utils import make_msgid

# have to split "[email protected]" into Address("name","name","domain.com"), and if multiple then have to string them together into tuple

holder = emails.strip().split('@')
if len(holder) != 2:
print("makeAddress: Invalid email id:",emails)
return os.environ.get('EMAIL_SENDER','')
return Address(holder[0],holder[0],holder[1])
elif type(emails) == list:
collector = []

holder = oneEmail.strip().split('@')
if len(holder) != 2:
print("makeAddress: Invalid email id:",oneEmail)
continue
collector.append(Address(holder[0],holder[0],holder[1]))
# after for loop:

@harshitsinghai77 use sendgrid or any email sending service you prefer. technically, you could also use your personal/professional email credentials to send emails. check out this guide of gmail |
