Stannp allows you to send snail mail via a web api. It includes postcards and letters. See stannp.com for more details.
pip install stannp
import the module and create an instance with your Stannp API Key
from stannp import StannpClient
STANNP_API_KEY="XXXXXXXXXXXX"
stannpinstance=StannpClient(STANNP_API_KEY)
# set recipient using a python dictionary
recipient={'title': 'Mr', 'firstname':'Andy', 'lastname':'Pi', 'address1': 'My House', 'address2': 'My Town', 'city':My City', 'postcode': 'Postcode', 'country':'GB'}
# Set the message text
message="Hi Friend,\n\n This is a sample postcard using AndyPi's stannp-api wrapper for python"
# Creates the postcard (where test.jpg is the filename of the front of the card)
card=stannpinstance.send_postcard(size="A6", test=True, recipient=recipient, front="test.jpg", back=None, message=message, signature=None)
# Prints the JSON repsonse from the stannp server, including the URL of a PDF preview
print card
# set recipient using a python dictionary
recipient={'title': 'Mr', 'firstname':'Andy', 'lastname':'Pi', 'address1': 'My House', 'address2': 'My Town', 'city':My City', 'postcode': 'Postcode', 'country':'GB'}
# Set the message text to be a PDF named test.pdf (note the first page will have the recipients address)
letter=stannpinstance.send_letter(test=True, template=None, recipient=recipient, background=None, pages="test.pdf", pdforhtml="pdf")
# print the URL of the preview PDF
