Email size requirements

Email size requirements vary depending on the email service provider, email client, and the recipient's email settings. Here are some general guidelines:

Email Service Providers (ESPs)

  1. Gmail: Gmail has a maximum email size limit of 25 MB (megabytes). However, it's recommended to keep attachments under 10 MB to ensure smooth delivery.
  2. Yahoo Mail: Yahoo Mail has a maximum email size limit of 25 MB.
  3. Outlook.com: Outlook.com has a maximum email size limit of 20 MB.
  4. Hotmail: Hotmail has a maximum email size limit of 10 MB.

Email Clients

  1. Microsoft Outlook: Microsoft Outlook has a maximum email size limit of 20 MB.
  2. Mozilla Thunderbird: Mozilla Thunderbird has a maximum email size limit of 10 MB.
  3. Apple Mail: Apple Mail has a maximum email size limit of 10 MB.

Recipient's Email Settings

  1. Email Server: Some email servers may have specific size limits for incoming emails. For example, some corporate email servers may have a limit of 5 MB.
  2. Email Client: Some email clients may have their own size limits for sending and receiving emails.

Best Practices

  1. Keep attachments small: Try to keep attachments under 1-2 MB to ensure smooth delivery.
  2. Use cloud storage: Consider using cloud storage services like Google Drive, Dropbox, or Microsoft OneDrive to share large files instead of attaching them to emails.
  3. Use email compression: Some email clients and services offer compression options to reduce the size of emails and attachments.
  4. Check email size before sending: Before sending an email, check the size of the attachment(s) to ensure it's within the recipient's email size limit.

Remember, it's always a good idea to check with the recipient's email settings and service provider to ensure that your email meets their size requirements.
