Using classic Outlook for Windows in educational settings
For bulk email from Outlook/Word, the supported Microsoft option in the provided guidance is Word Mail Merge.
- Install or use a MAPI-compatible email program such as Outlook.
- In Word, open or create the message to send.
- Go to Mailings > Start Mail Merge > E-mail Messages.
- Prepare a mailing list that includes a column for email addresses for every recipient.
- If using Excel, format ZIP/postal code columns as Text to preserve leading zeroes.
- If using Outlook contacts, Outlook must be the default email program and the same version as Word.
- Go to Mailings > Select Recipients and connect the mailing list.
- Add personalization fields with Mailings > Insert Merge Field.
- Preview the messages with Mailings > Preview Results.
- Send with Mailings > Finish & Merge > Merge to E-Mail.
- Choose the To field, subject, and whether to send as Text, HTML, or Attachment.
- Merge to E-Mail is unavailable if a default email program is not selected.
- Selecting Mail Merge To Outbox places the messages in Outbox.
For larger-scale mass mailings, the provided Microsoft guidance recommends using resources outside Microsoft 365 for bulk email, such as:
- on-premises email servers, or
- a non-Microsoft bulk email provider.
Also keep the recipient database clean by removing incorrect or non-existent email aliases to reduce bounces and protect deliverability.
If the bulk email is promotional, bulk sender requirements include:
- authenticate email domains,
- provide a visible unsubscribe link,
- enable one-click unsubscribe,
- keep spam rates low,
- do not use gmail.com or yahoo.com as the From address for bulk mailing.
