Why Your Emails Land in Spam (and How to Fix It)

Your emails are being sent, but they're not landing. Before you blame the tool, know this: spam placement is a stack of signals, and each one moves the filter. Here's how to diagnose yours, in order of impact.

1. Check your infrastructure (SPF, DKIM, DMARC)

The cheapest, most fixable causes are authentication failures:

• SPF — a TXT record listing which servers may send for your domain
• DKIM — a signature proving the mail wasn't tampered with
• DMARC — a policy telling receivers what to do with unauthenticated mail

How to check: send a test email and inspect the headers (or use a deliverability tool). If spf=pass, dkim=pass, and dmarc=pass aren't all true, fix that first. Providers that offer SMTP relays (SES, Mailgun, Google Workspace) usually have one-click records.

2. Check your sender identity

• Does the From domain match the domain you authenticated? Sending From: [email protected] through a relay that only authorizes mail.yourcompany.com is a mismatch filters notice.
• Is the From name human ("Alex @ Acme") rather than generic ("no-reply")? Low-reply senders get scored down.

3. Check your list health

Filters see your bounce and complaint history before they see your content:

• Bounces — a hard bounce rate above ~2–5% is a strong negative signal. If your list was "verified" by a third party and still bounces 15–25%, that list was never really verified.
• Complaints — more than ~0.1% of recipients marking you as spam is corrosive.
• Old/inactive addresses — sending to addresses that haven't opened in 6+ months risks both bounces and complaints.

Fix: verify recipients before send, remove hard bounces immediately, and trim inactive segments.

4. Check your volume curve

Filters score behavior over time, not a single send. The classic red flags:

• Sudden spikes (0 → 5,000 overnight)
• Identical volume at the same minute every day (machine-like)
• Sending more per mailbox than the provider's limits

Fix: ramp up gradually and pace delivery. For cold outreach, 10–50 emails/day per mailbox is the sane range; use per-task rate limits to enforce it.

5. Check your content

Spam filters read content, but modern ones read patterns more than words:

• Avoid classic trigger phrasing — "guaranteed", "100% free", "act now", excessive exclamation marks, ALL CAPS
• One link, one CTA — link-heavy mail scores worse; use a plain-text domain link and a calendar link at most
• Plain-ish beats HTML-heavy — multi-image, template-heavy mail with tiny text reads as bulk
• Include an unsubscribe — mail that can't be opted out of is filtered harder (and legally risky)

6. Check engagement (the honest way)

Open and click rates are the last layer. If people don't open, filters assume irrelevance:

• Open rate under ~20% — your subject or sender identity isn't earning attention (or your opens are being tracked through proxy servers, which undercounts)
• Click rate under ~2% — your CTA or offer isn't relevant to the list
• No replies — the single best "this is human mail" signal. Write like a person, ask a real question, follow up on opens only.

On open tracking accuracy: privacy features (mail client proxies) mean open pixels undercount. Treat clicks and replies as your reliable engagement signals.

The 15-minute triage

1. Send a test and verify SPF/DKIM/DMARC pass → fix if not
2. Confirm From domain matches your authenticated domain
3. Check last 1,000 sends: bounce rate and complaint rate → verify + prune if high
4. Look at your volume curve last 7 days → ramp/pause if spiky
5. Send a plain-text test to Gmail + Outlook → still spam? Simplify content and re-check DNS

Deliverability is a system, not a switch. GQ CRM handles the mechanical parts — verification, pacing, per-recipient tracking, bounce classification — so you can focus on the human parts: the list, the message, and the offer.
