I am trying to write a script that will scan through all emails from the past year. I can only get it to download the top 3. The tutorial I am following doesn't explain anywhere I can change the number of emails it downloads. Here's the code so far.

# user credentials
email_user = input('Email: ')
email_pass = input('Password: ')

# connect to imap
mail = imaplib.IMAP4_SSL("imap.gmail.com",993)

#login
mail.login(email_user, email_pass)

#select folder
mail.select("INBOX","SPAM")

#filter emails by header with receipt or invoice
type, data = mail.search(None, '(SUBJECT "Invoice")')
mail_ids = data[0]
id_list = mail_ids.split()

for num in data[0].split():
    typ, data = mail.fetch(num, '(RFC822)' )
    raw_email = data[0][1]
# converts byte literal to string removing b''
    raw_email_string = raw_email.decode('utf-8')
    email_message = email.message_from_string(raw_email_string)
# downloading attachments
    for part in email_message.walk():
        # this part comes from the snipped I don't understand yet... 
        if part.get_content_maintype() == 'multipart':
            continue
        if part.get('Content-Disposition') is None:
            continue
        fileName = part.get_filename()
        if bool(fileName):
            filePath = os.path.join('/Users/benbuechler/Desktop/Keepr Receipt Storage', fileName)
            if not os.path.isfile(filePath) :
                fp = open(filePath, 'wb')
                fp.write(part.get_payload(decode=True))
                fp.close()
            subject = str(email_message).split("Subject: ", 10)[1].split("\nTo:", 10)[1]
            print('Downloaded "{file}" from email titled "{subject}"'.format(file=fileName, subject=subject))

for response_part in data:
        if isinstance(response_part, tuple):
            msg = email.message_from_string(response_part[1].decode('utf-8'))
            email_subject = msg['subject']
            email_from = msg['from']
            print ('From : ' + email_from + '\n')
            print ('Subject : ' + email_subject + '\n')
            print(msg.get_payload(decode=True))

  • What is the output of `print(len(id_list))`? – mkrieger1 May 15 '22 at 22:31
  • sorry I don't see that in my code? edit* lol I realized what you meant I got none and 5 – Ben Buechler May 15 '22 at 22:38
  • code search in `"INBOX","SPAM"` and select only mails with `(SUBJECT "Invoice")` - maybe you don't have more mails which match these criterias – furas May 15 '22 at 23:12

    (@furas "Criteria" is the correct plural; the singular is "criterion".) – tripleee May 16 '22 at 04:29

    You mustn't assume that the byte string you receive is UTF-8; very often it will not be. The correct way to convert bytes to an email message is `message_from_bytes` – tripleee May 16 '22 at 04:31

    Apparently you have only 5 messages which contain "Invoice" and out of those, only 3 are multipart messages. Maybe see https://stackoverflow.com/questions/48562935/what-are-the-parts-in-a-multipart-email/48563281#48563281 – tripleee May 16 '22 at 04:35
