Why are my emails going to spam?

Your emails go to spam because inbox providers score how recipients treat your mail, and something is dragging that score down: junk sign-ups who never open, too few positive signals like replies, or a complaint rate creeping past 0.1%. Fix the intake, farm genuine engagement, and the algorithm re-files you into the primary inbox.

Around 15% of perfectly legitimate email never reaches the primary inbox. If you’re a coach emailing offers, that’s real revenue quietly evaporating, and the fix compounds like an investment: do the work once, collect the dividends monthly. Here’s the maths: a 10,000-person list at a 15% open rate gets 1,500 pairs of eyes per send. Lift that to 20% with the fixes below and you’ve added 2,500 extra impressions a week at five sends, before your list grows at all.

Fix 1: stop junk at the front door

Deliverability starts on your opt-in page, before anyone sends anything. Two moves:

• Make joining slightly harder. My own opt-in makes you tick a checkbox that says, in plain words, you’ll be receiving frequent emails. The wrong people bounce off; the right people have just made a micro-commitment to open.
• Show the first email on the confirmation page. After sign-up, display exactly what subject line and email to go find. New subscribers who open and click email one start their history with you as engaged, and the throwaway addresses (a large share of unfiltered opt-ins) never make it in.

A smaller, cleaner list beats a big dirty one. It isn’t how big it is; it’s how you use it.

Fix 2: ask for a reply early

Gmail keeps a scorecard on your sending domain the way you keep a mental scorecard on a generous friend. Opens help, clicks help more, and a reply is the strongest positive signal a recipient can send: real people reply to real people, spam gets deleted.

So engineer replies where attention peaks: email two of your welcome sequence (email one delivers the freebie). One question does it: “what’s your biggest struggle with [the problem you solve]?” Every answer is a deliverability boost, market research, and sometimes the start of a sales conversation, in one move. More reply-driven plays are in the coach email strategy guide.

Fix 3: send consistently until your name is the subject line

Long-term senders get opened on the from-name alone; subscribers stop reading subject lines when they already trust the sender. Every one of those habitual opens feeds the scorecard, which improves placement, which produces more opens. This flywheel is slow to start and nearly impossible for competitors to copy, because most of them quit sending after three weeks. If daily writing is what’s stopping you, that’s a solved problem: build the AI system.

Fix 4 (advanced): hand-raiser sequences

The algorithm judges percentages, not totals. So instead of pitching your whole list, invite readers to raise their hand for a topic, and only the interested segment gets the sequence. On one creator’s list this produced 60–90% open rates and 5–20% click-through rates against industry norms of roughly 20% and 3%, and his emails now land in primary, every send. The engaged minority generates a near-perfect report card that lifts placement for the entire list.

The order of operations

1. Checkbox + confirmation-page filter on every opt-in (today).
2. Reply prompt in email two of the welcome sequence (today).
3. Authentication records and list scrubbing, per the full deliverability guide (this week).
4. Consistent daily-ish sending until your name outranks your subject lines (forever).
5. Hand-raiser sequences once traffic justifies them.

Deliverability is unsexy exactly the way compound interest is unsexy. Want the audit checklist I ran for every client? It’s in the newsletter archive, free.

Frequently asked questions

What spam complaint rate gets you blacklisted?

Trouble starts around a 0.1% complaint rate, one complaint per thousand emails. Google formally throttles bulk senders at 0.3%, but by then your reputation damage is done. Treat 0.1% as your ceiling.

Do junk sign-ups really hurt deliverability?

Badly. In my experience roughly two-thirds of unfiltered opt-ins are junk or throwaway addresses that never open anything. Every one of them tells Gmail your mail is unwanted, which drags delivery down for the subscribers who actually want you.

Does list size matter to the spam algorithm?

No, percentages do. Inbox providers score the share of recipients who open, click and reply, not the totals. A 500-person segment engaging at 60% sends a better signal than 10,000 people engaging at 12%. That insight (credit to email deliverability specialist Troy Ericson) is why hand-raiser sequences work so well.

How long until deliverability fixes show results?

Opt-in filtering and reply prompts start registering within a couple of weeks. Reputation from consistent sending compounds over months, which is exactly why it works: most senders never stay consistent long enough to earn it.
