Why air mail won't send an email with multiple bcc

AirMail, a popular email client, has a limitation when it comes to sending emails with multiple BCC (Blind Carbon Copy) recipients. This limitation is due to the way AirMail handles BCC recipients and the underlying email protocol.

Here's what's happening:

  1. AirMail's BCC limitation: AirMail has a built-in limit of 50 BCC recipients per email. This means that if you try to send an email with more than 50 BCC recipients, AirMail will not allow it.
  2. Email protocol limitations: The Simple Mail Transfer Protocol (SMTP) used by AirMail to send emails has its own limitations. SMTP allows for a maximum of 100 recipients per email, including both To and BCC recipients. This means that even if AirMail didn't have a built-in limit, the SMTP protocol would still prevent sending emails with more than 100 recipients.
  3. Security concerns: Sending emails with a large number of BCC recipients can be a security risk. Spammers often use BCC to send large volumes of emails to unsuspecting recipients, which can lead to email account compromises and spamming issues. To mitigate this risk, email clients like AirMail impose limits on BCC recipients.

To work around this limitation, you can try the following:

  1. Split your BCC list: If you need to send an email to a large number of BCC recipients, consider splitting your list into smaller groups and sending separate emails to each group.
  2. Use a different email client: If you need to send emails with a large number of BCC recipients, you may want to consider using a different email client that doesn't have this limitation.
  3. Contact AirMail support: If you're experiencing issues with sending emails with multiple BCC recipients, you can contact AirMail support to see if they can provide any workarounds or solutions.

Keep in mind that these workarounds may not be ideal, and it's always a good idea to follow best practices for email marketing and communication to avoid spamming and other issues.
