How to Send an HTML Email

Send HTML in email via PHP

It is pretty simple. Leave the images on the server and send the PHP + CSS to them...

$to = 'bob@example.com';

$subject = 'Website Change Request';

$headers  = "From: " . strip_tags($_POST['req-email']) . "\r\n";
$headers .= "Reply-To: " . strip_tags($_POST['req-email']) . "\r\n";
$headers .= "CC: susan@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=UTF-8\r\n";

$message = '<p><strong>This is strong text</strong> while this is not.</p>';

mail($to, $subject, $message, $headers);

It is this line that tells the mailer and the recipient that the email contains (hopefully) well-formed HTML that it will need to interpret:

$headers .= "Content-Type: text/html; charset=UTF-8\r\n";

Here is the link I got the information from... (link)

You will need security though...

Send HTML emails with Python

From Python v2.7.14 documentation - 18.1.11. email: Examples:

Here’s an example of how to create an HTML message with an alternative plain text version:

#! /usr/bin/python

import smtplib

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

# me == my email address
# you == recipient's email address
me = "my@email.com"
you = "your@email.com"

# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link"
msg['From'] = me
msg['To'] = you

# Create the body of the message (a plain-text and an HTML version).
text = "Hi!\nHow are you?\nHere is the link you wanted:\nhttp://www.python.org"
html = """\
<html>
  <head></head>
  <body>
    <p>Hi!<br>
       How are you?<br>
       Here is the <a href="http://www.python.org">link</a> you wanted.
    </p>
  </body>
</html>
"""

# Record the MIME types of both parts - text/plain and text/html.
part1 = MIMEText(text, 'plain')
part2 = MIMEText(html, 'html')

# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
msg.attach(part1)
msg.attach(part2)

# Send the message via local SMTP server.
s = smtplib.SMTP('localhost')
# sendmail function takes 3 arguments: sender's address, recipient's address
# and message to send - here it is sent as one string.
s.sendmail(me, you, msg.as_string())
s.quit()

How to Send A Complicated Email with Flutter Mailer Package

There are 2 aspects to this question.

How to set the stripo html.
How to adapt an html template. (Modify the content to change parts of the template)

To set the template simply do:

message.html =
'''<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
[... copy the complete template here ...]
</html>'''

Three quotes (''') instead of one quote (') allows text to span multiple lines.
To keep your code clean, you might want to create a new dart file: mail-template.dart and assign the html-template to a variable. Then include this file and assign the variable.

To replace parts of the template I would use .replaceAll on the template.

var nameFromSomeInput = 'Jane Doe';
var yourHtmlTemplate = '<html>Dear {{NAME}}</html>';
message.html = yourHtmlTemplate.replaceAll('{{NAME}}', nameFromSomeInput);

Note that replaceAll is easy and doesn't depend on any additional libraries. It is however slow. Especially if you replace multiple values by calling replaceAll multiple times.

Consider a template engine like: jinja in such cases.
