If emails you send from GARMTECH Business Email (or mailboxes hosted with GARMTECH) land in the recipient’s Spam/Junk folder, it does not always mean the email service is “blocked”. Spam placement depends on domain authentication (SPF/DKIM/DMARC), sending reputation, message content, and the recipient’s mail provider rules.
Use this checklist to improve deliverability.
1) Make sure SPF, DKIM and DMARC are enabled
Proper domain authentication is the #1 requirement for modern email delivery.
- SPF authorizes which servers are allowed to send mail for your domain.
- DKIM signs outgoing messages so recipients can verify they were not modified.
- DMARC tells recipients how to handle messages that fail SPF/DKIM and can enable reports.
These records are set in your domain DNS. If your domain uses GARMTECH nameservers (ns1.garmtech.com, ns2.garmtech.com, ns3.garmtech.com), you can manage DNS in Plesk. If you use external DNS (for example Cloudflare), add the TXT records there.
2) Send through the correct SMTP server (with authentication)
For best results, your email app should send via GARMTECH SMTP with login/password authentication.
- Outgoing server: SMTP‑SSL, port 465
- Authentication: enabled (username/password required)
- Server name: use your service server hostname (shown in My.GARMTECH for your email/hosting service)
Avoid sending through random third‑party SMTP servers, which often causes SPF/DKIM alignment issues.
3) Align the “From” address with your domain
- Use a real mailbox address from your domain as the From address.
- Avoid sending “From: yourdomain.com” while authenticating with another domain — many providers treat this as suspicious.
4) Check message content (simple improvements)
- Avoid “spam‑style” subjects (ALL CAPS, too many exclamation marks, misleading wording).
- Keep a good balance of text vs images; include a plain‑text version if possible.
- Do not attach executable files. Prefer links to files in Cloud Storage instead of large attachments.
- If you send newsletters, include an unsubscribe option and send only to recipients who opted in.
5) Reputation and sending behavior
- New domains should “warm up”: send gradually, not in large bursts.
- Remove invalid addresses (bounces) from your recipient list.
- Do not send to purchased lists. High complaint rates will damage reputation quickly.
6) Ask recipients to whitelist (when appropriate)
For business communication, it can help if the recipient:
- moves your email from Spam/Junk to Inbox, and
- adds your address/domain to their safe sender list.
What information is useful if you still see spam placement
- A copy of the message header from the recipient side (if available).
- Which recipient provider flagged it (Gmail, Outlook, etc.).
- Whether SPF/DKIM/DMARC are already configured in DNS.
