tl-emailtools 1.1.0

A email-tool package simplified sending email.

emailtools-python3

A simple wrapper for standard lib -- email & stmplib

Simplify the steps of sending emails in Python, generate and send neatly formatted emails with just a few lines of code.

A simple example：

from PIL import Image
from emailtools import Email, EmailServer

img = Image.open("the_email_path")
mail = Email.sequence(
    "The subject",
    "# header-1",
    "paragraph", 
    "another paragraph",
    img,
    "# header-2",
    "another paragraph",
)
server = EmailServer.initFromJson("./emailserver.json")
server.send(mail)

The above code can be used to send emails. The content of the message can have headers, text, and tables. If pillow and pandas avaliable, image and DataFrame can add to mail.

config-file

Config file "./emailserver.json" (Of course you can use any name you like) contains mail-server-address, sender name, sender account and default receivers(optional). Format of config file is below：

{
    "host": "smtp.xxx.com",
    "addr": "[e-mail]",
    "name": "your_nick_name",
    "key": "password",
    "receivers": {
        "[e-mail]": "his/her_nickname"
    }
}

Dependency

• No essential dependency when running on Python3.12 In this case, only text and table can add to mail
• pillow needed when sending image
• pandas needed when sending DataFrame

How to use

1. Create Email instance. Email provides two ways to create a mail:

mail_subject = "theSubjectOfMail"

# By instantiating `Email` class
mail = Email(mail_subject)

# By class method
mail = Email.sequence(mail_subject)

Subject of mail is needed when creating mail.

2. Add content to mail by mail.add* methods.

# add header
mail.addHead("header1")             # h1 (default)
mail.addHead("header2", level=1)    # h1
mail.addHead("header3", level=2)    # h2

# add paragraph
mail.addParagraph("This is a paragraph.")

# add any text
# start with one '#' or more would be seemed as header
mail.addText("# header4")                   # h1
mail.addText("This is another paragraph.")  # paragraph

# add table (2d)
t = [ [1,2,3], [4,5,6] ]    
th = ["A", "B", "C"]        
tc = "table_caption"
mail.addTable(t, head=th, caption=tc) # head ana caption is optional

# add Image (avaliable when `pillow`)
from PIL import Image
img = Image.open("any.png")
mail.addImage(img)

# add DataFrame (avaliable when `pandas`)
import pandas as pd
df = pd.DataFrame(
    [ [1, 2, 3], [4, 5, 6] ], 
    columns=["A", "B", "C"]
)
mail.addDataFrame(df)

More convenient, use classmethod Email.sequence() to create mail with any number of content:

mail = Email.sequence(
    "The subject",          # Subject (essential)
    "# header-1",           # h1
    "paragraph",            # p
    "another paragraph",    # p
    img,                    # image
    "## header-2",          # h2
    "another paragraph",    # p
)

3. Init EmailServer . Specific your account, passwd and mail-server-address:

Cation: DO NOT write your account in public code

# use parameter
server = EmailServer(
    "smtp.xxx.com",             # address
    "local_nickname",           # local name
    "[e-mail]",  # local account
    "xxxxxxxxxxxxxxxxxxx",      # local key
)

# use config file
server = EmailServer.initFromJson("cfg.json")

Format of config file see this.

4. Send the mail

# send the mail
server.send(mail)

server will retain logging in. Auto log out when instance deleted. Manually log out is not needed.
