Need the TLDR version? Jump to the bottom here!<\/a><\/p>\n<\/div>\n\n

\n

You crafted the subject line. You wrote the copy. You hit send. And then nothing. Low opens, no clicks, zero replies. If that sounds familiar, there’s a good chance your emails aren’t reaching inboxes at all.<\/p>\n<\/div>\n\n

\n

Here’s what most people don’t realize: when deliverability breaks down, the cause is almost never the platform you’re sending from. It’s your sending domain’s reputation, and it’s something only you can fix.<\/p>\n<\/div>\n\n

\n

What “going to spam” actually means<\/strong><\/h2>\n<\/div>\n\n
\n

When an email lands in spam, it’s not random. Inbox providers like Gmail, Outlook, and Apple Mail use filters that evaluate your emails in real time, and they’re getting smarter every year.<\/p>\n<\/div>\n\n

\n

These filters consider two things: technical signals<\/strong> (does this email come from a trustworthy source?) and engagement signals<\/strong> (do people actually want to read this?). If either is off, your emails get flagged before your subscriber ever sees them.<\/p>\n<\/div>\n\n

\n

The fix depends on which category is causing the problem, so let’s walk through both.<\/p>\n<\/div>\n\n

\n

The thing most people get wrong: platform reputation vs. your domain reputation<\/strong><\/h2>\n<\/div>\n\n
\n

Deliverability is a shared responsibility, and it\u2019s worth understanding who controls what. <\/p>\n<\/div>\n\n

\n

Inbox providers consider two types of reputation: IP reputation (tied to the sending platform’s infrastructure) and domain reputation (tied to your sending domain). Both matter, but they are not weighted equally. Domain reputation carries significantly more influence over where your emails land.<\/p>\n<\/div>\n\n

\n

Your sending domain (the part after the @ in your email address) builds its own reputation over time based on how recipients interact with your emails. Spam complaints, low open rates, bounces, and sending to people who never asked to hear from you. All of that is tied to your domain, not the platform you send from.<\/p>\n<\/div>\n\n

\n

On the IP side, Flodesk actively manages our shared sending pools to keep them healthy. We monitor sending behavior across the platform and take steps to ensure that members with poor sending habits aren’t damaging pools used by members who are doing everything right .Of all the emails sent across our platform, only 0.1% bounce due to IP reputation\u2014a direct result of how actively we manage our sending pools. Your domain reputation is where the real work happens.<\/p>\n<\/div>\n\n

\n

When deliverability breaks down, the cause is almost always the same: domain reputation that’s been damaged by sending behavior.<\/strong> Switching platforms won’t fix it. Cleaning up your sending habits will.<\/p>\n<\/div>\n\n

\n

The good news is that domain reputation isn’t permanent. It responds to consistent, quality sending, and the steps below are exactly what moves the needle.<\/p>\n<\/div>\n\n

\n

The unlimited subscriber trap<\/strong><\/h2>\n<\/div>\n\n
\n

For the first seven years, Flodesk didn\u2019t charge by subscriber count, and for most members, that was a genuine advantage. But it can quietly create an environment for bad habits, which can lead to a deliverability problem if you’re not paying attention.<\/p>\n<\/div>\n\n

\n

When there’s no cost tied to list size, there’s little urgency to clean it. Thousands of unengaged subscribers sit on a list indefinitely. Emails keep going out to people who stopped opening months ago. Inbox providers notice, and your domain reputation takes the hit for every email that gets ignored, deleted, or marked as spam.<\/p>\n<\/div>\n\n

\n

Platforms that charge by subscriber count tend to see better list hygiene simply because there’s a financial reason to remove people who aren’t engaging. When it’s unlimited, that incentive disappears. Lists quietly accumulate dead weight and poor sending habits.<\/p>\n<\/div>\n\n

\n

Think of your list less like an asset to accumulate and more like a garden to tend. The subscribers who are actively engaging are the ones doing the work to build your reputation. The ones who aren’t? They’re quietly working against it.<\/p>\n<\/div>\n\n

\n

A smaller, engaged list will always outperform a large, disinterested one, in deliverability and in results.<\/p>\n<\/div>\n\n

\n

Technical reasons your emails land in spam<\/strong><\/h2>\n<\/div>\n\n
\n

You’re sending from a free email address<\/strong><\/h3>\n<\/div>\n\n
\n

Sending from a Gmail, Yahoo, or Hotmail address is one of the fastest ways to hurt your deliverability. In 2024, Google and Yahoo formalized requirements that bulk senders must use a custom domain\u2014and it’s one of the first things spam filters check. Free email addresses are the calling card of spammers, which means legitimate business emails sent from them get caught in the same net.<\/p>\n<\/div>\n\n

\n

The fix: use a custom domain email (like hello@yourbrand.com) for all your email marketing and make sure the domain is properly authenticated. This also makes your brand look more polished and builds trust with your subscribers from the very first email they receive.<\/p>\n<\/div>\n\n

\n

Your domain authentication isn’t set up<\/strong><\/h3>\n<\/div>\n\n
\n

Email authentication tells inbox providers that you are who you say you are. Without it, your emails look suspicious, even if your content is perfectly legitimate.<\/p>\n<\/div>\n\n

There are three records to know:<\/p>\n<\/div>\n\n
