Despite its frequency of use, the process of adding attachments to an email can vary slightly depending on the email service used, potentially causing confusion.

Master the art of sending email attachments

Sending email attachments is an essential business and personal skill, allowing you to share documents, images, and other file types quickly and efficiently. However, there are several aspects to consider to ensure the process goes smoothly. First, it is important to know the attachment size limit imposed by your email service provider, because sending a file that is too large may result in it being rejected. For example, Gmail limits the size of attachments to 25 MB per email. If you need to send a larger file, you can use file sharing services or compress the file to reduce its size.

Additionally, it is crucial to ensure that the files you send do not contain viruses or malware, as this could not only compromise your security, but also that of your recipient. Always make sure your antivirus software is up to date and has scanned the files before attaching them to your email. Additionally, consider the file format of your attachments. Some formats may not be accessible to the recipient depending on the software or device they are using, so it is a good idea to check or convert your files to a more universal format like PDF for text documents or JPEG for the pictures.

Example of sending an email with attachment in Python

Using Python with the smtplib library and email.mime

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
msg = MIMEMultipart()
msg['From'] = 'votre.email@example.com'
msg['To'] = 'destinataire@example.com'
msg['Subject'] = 'Sujet de l'email'
body = 'Ceci est le corps de l'email.'
msg.attach(MIMEText(body, 'plain'))
filename = "NomDuFichier.pdf"
attachment = open("Chemin/Absolu/Vers/NomDuFichier.pdf", "rb")
part = MIMEBase('application', 'octet-stream')
part.set_payload((attachment).read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', "attachment; filename= %s" % filename
msg.attach(part)
server = smtplib.SMTP('smtp.example.com', 587)
server.starttls()
server.login(msg['From'], 'votreMotDePasse')
text = msg.as_string()
server.sendmail(msg['From'], msg['To'], text)
server.quit()

The keys to effectively sending attachments

Adding attachments to an email may seem simple, but there are several tips that can improve your efficiency and ensure the security of your sending. Firstly, it is essential to check the format of the attached files. Some formats, such as Word or Excel documents, can be edited by the recipient, which is not always desirable. To preserve the integrity of the document, consider converting these files to PDF. Second, the issue of security is paramount. Attachments may carry viruses or malware. It is therefore recommended to scan all files with antivirus software before attaching them to your email.

Additionally, the size of attachments is a key factor to consider. Many email service providers limit the size of emails, including attachments, which may require compressing files or using online storage services for larger files. It is also a good idea to name your files clearly to make them easier for the recipient to identify. Finally, take the time to write a clear message indicating the content and importance of the attachments. This extra step can greatly help the recipient understand the context of your submission and process the files appropriately.
