Let’s talk about the thing nobody wants to admit: A lot of email deliverability problems aren’t caused by the inbox providers for no reason—they’re caused by ghosting your email list.

That doesn’t mean you need to email daily like you’re posting on the ‘gram, but you do need to keep a regular cadence to avoid the spam folder for your emails.

But inbox providers don’t look at silence as “you’re booked out and thriving.”—all they see is you suddenly sending mass emails out of nowhere, and they think you’re a scammer because you don’t have a relationship with your subscribers. It’s giving “Who is this and why are they suddenly yelling into the inbox?”

And subscribers? They forget who you are because you never email them, and then they think, “Wait…did I sign up for this?” That’s when you get the dreaded delete, unsubscribe, or worst-case: spam complaint.

So yes—emailing regularly matters for sales because trust needs to be built over time, and inbox placement is a long-term relationship with your subscribers and inbox providers.

Deliverability is a Trust Score

Email deliverability is simply: where your email lands—inbox, promotions tab, spam, or blocked entirely.

And while you can’t control everything, you can control the things inbox providers use to decide if you’re trustworthy: Your authentication setup, complaint rate (or lack thereof), your engagement signals, and your sending behavior over time.

The big inbox providers have been getting louder about requirements for people who send email at scale (yes, you’re considered “big” even if you just have a hundred people on your list), especially around authentication and easy unsubscribing.

Deliverability isn’t just about writing better subject lines to increase your open rates; it starts before your subscribers even pen their emails.” Inbox providers watch reputation, engagement, and patterns to decide whether you’re legit or a scammer who’s going to blast newsletters filled with spam because they’re trying to protect their users from junk and scams. So they look for signals that your emails are wanted and legitimate.

Two of those signals you can influence immediately: engagement (opens, clicks, replies, saves, moving you to primary, etc.) and consistency (a stable sending pattern that doesn’t look like random bursts of energy similar to cat zoomies). Sudden send volume spikes and inconsistent frequency can raise red flags and make inbox providers think you’re up to no good.

That’s not to say you can’t take a break for a week here or there. The key is to keep the regular cadence of newsletters sent out weekly, the majority of the time, so when life happens, it’s not the end of the world if you don’t email. Then your sender reputation doesn’t reset to “stranger danger” every time you disappear.

You Have to Earn Double Trust: Your Subscribers + Inbox Providers

This is the part that makes consistency such a powerful strategy for email marketing—the same behavior that builds trust with people also builds the engagement signals that help your deliverability. If subscribers forget you, they won’t open, let alone click a link in one of your emails, or reply back. And if you only email when you’re launching, you’re training your audience to associate your name with “someone is about to ask me for money.” That doesn’t make you a scammy business. But it does make your emails easy to ignore because all you do is sell to your audience and never build trust with them.

And a list full of subscribers who ignore your newsletters has great consequences, like: lower open rates, fewer click-throughs, less replying, more deletes without reading your emails, etc. And all of those things tell inbox providers, “this sender isn’t sending emails people want.”

The risk comes with the cycle of your subscribers never opening continuing and making your deliverability get worse: you don’t email consistently → people forget you → fewer opens → inbox providers trust you less → you land in spam/promotions more → even fewer opens → you panic and email less → repeat forever until you cry.

What “Email Regularly” Actually Means

A regular newsletter does not mean daily. Consistency matters more than frequency for email deliverability.

A consistent weekly email will always beat a chaotic “I email five times this week, then vanish for a month,” because you’re building a sending history with stable behavior. You’re also building a relationship rhythm with subscribers, so your name stays familiar and top of mind for when they need help with the problem you solve. Sudden spikes in sending are when problems arise with deliverability.

Email Marketing Non-Negotiables That Support Deliverability

Email consistency helps with a large percentage of deliverability problems, but it’s not the only lever you can pull to help. If your technical foundation is messy, you can email every week and still end up in the spam folder.

Authenticate your domain (SPF, DKIM, DMARC)

Authentication is how you prove your emails are actually coming from you, not someone spoofing your domain. If you’re sending “bulk” mail (basically, if you’re trying to sell something from emails, consider yourself bulk), you need these three records on your domain to authenticate it.

Make unsubscribing easy (one-click expectations)

Your email service provider (ESP) should make it easy to implement one-click unsubscribe, but don’t try to cheat the system and hide your unsubscribe links with fonts that blend in with your newsletter background. Not only is this an accessibility issue, but you also want someone to unsubscribe if they no longer want your emails.

This will help your deliverability in two ways: one, it means your emails are only going to people that want them, but it also prevents them from marking your emails as spam, which will hurt your deliverability, unlike unsubscribes, which don’t.

I know unsubscribes sting, but fighting unsubscribes makes deliverability worse, not better. If someone doesn’t want your emails anymore, the best outcome is that they unsubscribe.

Keep spam complaints low

Google has a threshold used in its bulk sender ecosystem: keep user-reported spam rates below 0.3%. That’s why you don’t want to keep emailing people who don’t want to hear from you or have gone cold. You need to clean them off your list and make it easy for people to unsubscribe so you don’t get marked as spam.

How to Email More Without Annoying Your List

If you’re scared to email regularly because you think people will hate you, here’s the easy fix: make your emails worth opening. Value-filled emails don’t mean “never mention your offer.” Value means your emails give them something useful or enjoyable and make your subscribers think, “Oh, she gets me!”

Examples of emails that build trust:

• A quick win tip (something they can implement in 5 minutes)
• A behind-the-scenes story with a lesson (not a diary entry)
• A teardown (what you’d change on a sales page/email)
• A myth-buster (what’s not working anymore)
• A “steal this” template snippet

Then, when you sell, it feels natural because you’ve already been showing up and helping. This also helps deliverability because engaged subscribers are less likely to ignore you and more likely to click and reply.

Email List Hygiene

If you keep emailing the same unengaged people forever because “bigger list = better.” you’re going to end up in spam eventually. Unengaged subscribers never help your email marketing strategy. If someone hasn’t opened in months, continually emailing them can drag down your engagement averages and increase your chances of spam complaints.

Run subscribers who haven’t opened your emails in 90 days through a re-engagement sequence. If they don’t respond, unsubscribe them from your email list and call it a day. Your list will be healthier without the vanity metrics of more subscribers.

Avoid Sudden Sending Volume Spikes After Long Silence

If you’ve been quiet and then you email your entire list with a promo, that’s a classic recipe for: low engagement (because they forgot you), higher complaints (because they’re surprised), and spam folder risk (because the pattern looks like a burst)

If you’ve been Inconsistent, here’s how to restart: Start by emailing the people most likely to open: your most recent openers/clickers, customers, new subscribers, etc. Let those good engagement signals lead the way. Then gradually expand to the rest of the list over the next few sends.
