Trying to send messages to my Women's Institute members. Keep being blocked as it's been decided I'm sending spam messages. Unfortunately, same message to all members. How do I get past this?

    Hi Ron,

    Good day. Getting blocked is part of the designed system of email providers every time it sees identical messages. This usually happens if the provider sees these characteristic on your mails like:

    1. identical content.
    2. many recipients in a short time.
    3. possibly using CC instead of proper bulk methods.
    4. no prior sending reputation (or low trust).

    Try to send emails in an opposite behavior from the mentioned characteristics above.

    1. Use BCC if it's a small group. Put all members in the BCC section. Try to send in small batches like 10 to 15 at a time. Send this every 10 to 15 minutes after every batch.
    2. Slightly personalize or vary the content of the messages.
    3. Avoid spam patterns like: attached with too many links, mail subject with ALL in capital letters and others.
    4. Check your account status. If your account is temporarily flagged, wait for 24 hours before sending again. Repeated attempts can worsen the block.

    I hope this works.

    Regards,
    Jhun

    Outlook’s spam protection can mistake bulk messages (same content to many recipients) as junk. To improve deliverability when emailing your group:

    1. Ask members to add the sending address to their Safe senders list
      • In Outlook/Outlook.com, recipients can add the address to Safe senders so future messages are less likely to be treated as spam. See the guidance in “Safe Senders in Outlook.com”.
    2. Avoid “bulk send” patterns that look like spam
      • Do not put all recipients in BCC.
      • Avoid sending too many emails at once or to too many people at the same time. If possible, split the list into smaller groups and send in batches.
      • Do not repeatedly send to people who never read or reply to the emails.
    3. Keep message content simple and safe
      • Avoid using scripting or complex HTML; Outlook.com may strip or treat some HTML as unsafe.
      • Keep subject and body clear and relevant (e.g., meeting notices, agendas) and avoid “spammy” wording.
    4. Use Outlook’s built‑in junk controls correctly
      • Ensure members mark any misclassified messages as “Not junk” in their mailbox so the filter learns.
      • You can also rely on Outlook’s Junk E‑mail Filter, which automatically evaluates incoming messages and routes suspected spam to the Junk E‑mail folder.
    5. General anti‑spam hygiene
      • Do not respond to suspicious emails requesting personal information, and avoid forwarding chain emails; this helps keep the overall reputation of accounts better and reduces the chance of being treated as spam.

    If messages are still being blocked at the service level (for example, if recipients use Outlook.com and your mail is being treated as spam by Microsoft’s systems), ask an IT‑savvy contact or your email provider to review sender reputation and volume patterns against Microsoft’s sender guidelines.
