If you wish to ship emails in Python, use a dependable and safe electronic mail API resolution. On this article, you’ll be taught the step-by-step strategy of sending emails in Python utilizing the API methodology.
Establishing E mail API
To streamline electronic mail sending in Python, you should use a transactional electronic mail service similar to Mailtrap, Gmail API, Sendgrid, and so forth. And, an API additionally lets you automate a lot of electronic mail sending
Now, I’ll present you easy methods to ship several types of emails (plain textual content, electronic mail with attachments, HTML emails) and electronic mail a number of recipients in Python utilizing an email API Earlier than that, let’s perceive easy methods to arrange an electronic mail API:
- Select an electronic mail API: To get began, select an electronic mail API in accordance with your preferences. Be sure that it presents Python SDKs to ship automated emails (for instance Mailtrap’s Python SDK).
- Enroll: Signal as much as the chosen electronic mail API supplier.
- Join and confirm your area: Subsequent, join and confirm your area with the e-mail API service supplier you’ve chosen. If not verified, it is possible for you to to ship emails to the account proprietor’s electronic mail handle solely.
This ensures recipients solely obtain real emails, avoiding spam. Primarily based on the service supplier, full area authentication.
- Set up electronic mail API library: Let’s name our electronic mail API – “MyEmailAPI”. Make sure the Python app is put in in your system after which set up MyEmailAPI’s Python SDK utilizing the under command:
pip set up myemailapi
Ship a Plain Textual content E mail
Step 1: Create your mail object and fill within the variables
1 |
import myemailapi |
2 |
|
3 |
# Create a mail object
|
4 |
|
5 |
mailobj = Mail( |
6 |
newsender= Tackle(email1=“testmail@area.com”, identify=“Check Sender”), |
7 |
to=[Address(email1=“reciever@example.com”, name=“Test Receiver”)], |
8 |
newsubject=“Check electronic mail”, |
9 |
newtext=“This is a plain-textual content electronic mail.”, |
10 |
)
|
Now, create the e-mail shopper utilizing your API tokens by:
- Opening your electronic mail API account
- Discovering API tokens and copying the credentials
Step 2: Ship your message
# Outline electronic mail API shopper and ship electronic mail
1 |
emailclient = MyEmailAPIClient(newtoken=“new-api-key”) |
2 |
emailclient.ship(mailobj) |
Right here’s the whole code snippet:
1 |
from myemailapi import Mail, EAddress, MyEmailAPIClient |
2 |
mailobj = Mail( |
3 |
# Outline sender handle and identify
|
4 |
newsender=Tackle(email1=“testmail@area.com”, identify=“Check Sender”), |
5 |
# Outline receivers
|
6 |
to=[Address(email1=“receiver@example.com”, name=“Test Receiver”)], |
7 |
# E mail topic
|
8 |
newsubject=“Check electronic mail”, |
9 |
# Outline plain textual content
|
10 |
newtext=“Hello,/nThis is a plain-textual content electronic mail.”, |
11 |
)
|
12 |
|
13 |
# Outline MyEmailAPIClient utilizing your API keys
|

print(“Congrats! You’ve efficiently despatched your first plain textual content electronic mail in Python.”) |
Ship an HTML E mail
Observe the directions to send an HTML email:
- Specify the HTML Parameter: Specify the ‘html’ parameter for the article – “Mail”. That is the place you’ll maintain the HTML content material you create. E mail purchasers that may show HTML will render this electronic mail part.
- Fallback Textual content Content material: If an electronic mail shopper can’t render HTML content material, the plain textual content you’ll outline inside the e-mail might be used because the fallback. That is additionally helpful for end-users preferring pure text-based emails.
Right here’s the complete code snippet for sending a Python electronic mail with HTML content material:
1 |
from myemailapi import Mail, EAddress, MyEmailAPIClient |
2 |
|
3 |
mailobj = Mail( # Create the Mail object for the HTML electronic mail |
4 |
# Outline sender handle and identify
|
5 |
newsender=Tackle(emailaddress=“testmail@area.com”, identify=“Check Sender”), |
6 |
# Outline receivers
|
7 |
to=[Address(emailaddress=“receiver@example.com”, name=“Test Receiver”)], |
8 |
# Outline electronic mail topic
|
9 |
newsubject=“HTML electronic mail”, |
10 |
# Outline textual content
|
11 |
newtext=“Hello,/nEmail shopper can’t render HTML? Use this fallback textual content.”, |
12 |
html_text=“”” |
13 |
<html> |
14 |
<head> |
15 |
<title>Titletitle> |
16 |

27 |
emailclient = MyEmailAPIClient(newtoken=“new-api-key”) |
28 |
|
29 |
# Ship your HTML electronic mail
|
30 |
emailclient.ship(mailobj) |
31 |
|
32 |
print(“Congrats! You’ve efficiently despatched your first HTML electronic mail.”) |
Ship E mail to A number of Recipients
Observe the under directions:
- A number of Recipients Configuration: I’ll change the recipient part to arrange the e-mail for extra recipients. As a substitute of utilizing just one ‘to’ handle, we’ll use a number of addresses.
- Setting the ‘To’ subject: Within the under code, we’ll outline two recipient addresses for the ‘To’ field- receiver1@example.com and receiver2@example.com. As well as, we’ll outline names for every recipient – Check Receiver 1 and Check Receiver 2.
Right here’s the whole code for sending an electronic mail to a number of recipients in Python:
1 |
from myemailapi import Mail, EAddress, MyEmailAPIClient |

emailclient.ship(mailobj) |
23 |
|
24 |
print(“Congrats! You’ve efficiently despatched emails to a number of recipients in Python.”) |
Ship E mail With Attachments
Observe the under directions:
- Specify the file path: First, specify the file path for the attachments. The code will learn the file content material as bytes to make sure every attachment has correct encoding. This fashion, attachments are transmitted securely over the community.
- Encode in Base64: Guarantee to encode the file content material in base64 to guard it from malicious actors as electronic mail protocols lack binary-safe options. If you encode your file content material, the binary knowledge might be transformed into textual content for safe transmission. Use the next methodology to encode the file content material:
base64.b64encode
- Create the file Attachment: Create the Attachment class occasion with the next parameters:
- disposition_new: To point the file as an attachment, the ‘disposition_new’ is about to ‘Disposition.ATTACHMENT’.
- content_new: It represents the file content material encoded in base64
- mimetype_new: The parameter indicators electronic mail purchasers in regards to the file sort.

from pathlib import Path |
4 |
|
5 |
# Outline recordsdata to connect
|
6 |
filepath = Path(“thisis/your/filepath/abc.pdf”) # Insert your file’s identify |
7 |
filecontent = filepath.read_bytes() |
8 |
|
9 |
# Base64 is used to encode the content material of the file
|
10 |
encodedcontent = base64.b64encode(filecontent) |
11 |
|
12 |
# Specify the e-mail object with an attachment
|
13 |
mailobj = Mail( |
14 |
# Outline sender handle and identify
|
15 |
newsender=Tackle(emailaddress=“testmail@area.com”, identify=“Check Sender”), |

print(“Congrats! You’ve efficiently despatched emails with an attachment.”) |
Check E mail Earlier than Sending
Earlier than you ship bulk emails utilizing an electronic mail API service, be sure to check it beforehand on a check server. That is much like testing a brand new software or rolling out a brand new characteristic in your app.
An electronic mail testing API will work like a third-party internet server. You’ll get a safe staging atmosphere the place you may deal with your electronic mail site visitors internally and examine if the e-mail sending performance is working advantageous. You may also detect and resolve bugs and errors earlier than sending your emails to focused recipients. As well as, you may preview and consider your electronic mail content material throughout completely different gadgets and electronic mail purchasers with the intention to optimize your message.
In consequence, you’ll be capable of:
- Ship emails to the precise recipients and improve electronic mail deliverability
- Keep away from spamming recipients with too many check emails
- Forestall sending emails with damaged hyperlinks, particularly in transactional emails like subscription affirmation emails
- Safeguard your area status by stopping area blacklisting or getting larger spam scores
Thus, earlier than you ship your emails, ship them to a delegated electronic mail handle utilizing an electronic mail testing API. View the e-mail content material, examine hyperlinks, repair points, after which solely ship your emails to the target market.
Within the under part, I’ll present you easy methods to check an electronic mail utilizing a hypothetical electronic mail testing API – ‘EtestAPI’. Right here’s easy methods to get began step-by-step:
- Hook up with the EtestAPI shopper
- Outline electronic mail content material – topic, textual content, attachments (if any), sender, and receiver(s)
- Generate a POST request to EtestAPI utilizing your knowledge and API token.
Right here’s the complete code to check your electronic mail utilizing EtestAPI:
1 |
# Import ‘json’ and ‘requests’ libraries for dealing with JSON knowledge and HTTP requests
|
2 |
import requests |
3 |
import json |
4 |
|
5 |
# Outline a perform ‘test_my_email’ with parameters for electronic mail testing
|
6 |
def test_my_email(etestapi_token1, inbox_id1, sender_email1, recipient_email1, topic, textual content): |
7 |
url = f"https://api.etestapi.com/v1/inboxes/{inbox_id1}/messages" |
8 |
headers = { |
9 |
"Authorization": f"Bearer {etestapi_token1}", |
10 |
"Content material-Kind": "software/json", |
11 |
}
|
12 |
|
13 |
knowledge = { |
14 |
"from": [{“sender_email1”: “sender@domain.com”, “name”: “Test Sender”}], |
15 |
"to": [{“recipient_email1”: “receiver@example.com”, “name”: “Test Receiver”}], |
16 |
"topic": “E mail Check”, |
17 |
"textual content": “Hello,/nLet’s carry out electronic mail testing”, |
18 |
}
|
19 |
|
20 |
|
21 |
# Convert knowledge to a JSON string
|
22 |
json_data = json.dumps(knowledge) |
23 |
|
24 |
# make a POST request utilizing ‘requests.submit’ to ship your electronic mail to EtestAPI and get the response in JSON
|
25 |
response = requests.submit(url, headers=headers, json_data) |
26 |
|
27 |
if response.status_code == 200: |
28 |
print("Congrats! Your electronic mail check is profitable!") |
29 |
print("The check electronic mail is shipped to EtestAPI inbox.") |
30 |
else: |
31 |
print(f"Check electronic mail failed: {response.status_code}") |
32 |
print(response.textual content) |
Rationalization:
- ‘url’: API endpoint URL is constructed
- ‘headers’: Headers are arrange, defining the kind of content material and API token
- response.standing.code: It helps you examine whether or not your electronic mail was efficiently despatched to the e-mail check API.
Summing Up
Utilizing a dependable and safe electronic mail API resolution lets you ship emails sooner, with out hassles. If you happen to run a enterprise, an electronic mail API will enable you automate the method. Thus, you may ship extremely customized and bulk emails rapidly with a couple of traces of code as we’ve talked about above.
