What Is a Good Email Deliverability Rate? Benchmarks by Category

What is a good email deliverability rate?

"Deliverability rate" gets used for 2 different numbers, and a good result looks different for each. Your email platform reports the first one by default. The second one you only see if you test for it.

• Delivery rate is the share of your emails that the receiving mail server accepted instead of bouncing. 95% or higher is the common benchmark, and the global average sits around 98.5%.

• Inbox placement rate is the share of those accepted emails that landed in the inbox instead of spam. The global average was 87.2% in 2025, and well-run programs reach 90% or more.

What you send changes the bar too. Transactional email, like receipts and password resets, should score higher than marketing email, because people expect it and open it.

A 98% delivery rate looks like a win on a dashboard, but it says nothing about the spam folder. If your inbox placement sits at 85%, about 15 of every 100 accepted emails never reach the inbox, while every report stays green. That gap between the 2 numbers is where opens, clicks, and revenue go missing.

This guide gives you the benchmarks for both numbers, broken down by what you send and by mailbox provider.

What's the difference between delivery rate and inbox placement rate?

Think of every email passing 2 checkpoints. The first is the mail server's front door: it either accepts your message or bounces it. A 98% delivery rate means 2% bounced, and that is the number your email platform reports by default. You'll find it in any email deliverability metrics dashboard.

The second checkpoint is the filter behind the door. Of the messages that got in, some reach the inbox and the rest go to junk, the promotions tab, or quarantine. Inbox placement measures that split, and you can't see it unless you test for it.

When someone says "our deliverability is 98%," they almost always mean delivery rate. They're measuring the front door and assuming the filter let everything through, which is how a program convinces itself it's healthy while part of its audience never sees a send.

Track both numbers, because delivery rate tells you whether your list and setup are working, and inbox placement tells you whether anyone reads your email.

What is a good email deliverability rate by sending type?

The right benchmark changes with what you send. Transactional email should score higher than marketing email, because lists are clean and recipients are waiting for the message. Holding both to one benchmark will let a weak transactional program off the hook.

Marketing email

Marketing email covers newsletters, campaigns, promotional sends, and drip sequences. A good delivery rate here is 95% or higher.

Inbox placement is the harder target. The global average reached 87.2% in 2025, up 3.7 points from 83.5% in 2024. Good programs beat the average and aim for 90% or more.

If delivery drops below 95% or inbox placement falls under the 80% minimum, you have a list or reputation problem, and it needs attention before your next send. Our guide to Gmail deliverability issues walks through the most common causes at the biggest mailbox provider.

Transactional email

Transactional email covers password resets, order confirmations, shipping notifications, and receipts. Jam7 sets the transactional bar at 97 to 99%, higher than for marketing, and flags anything below 95% for investigation.

The reasons are easy to see from the mailbox provider's side. People want these messages, so complaint rates stay low. Lists stay clean because every address belongs to someone who just signed up or bought something. And recipients open them quickly, which keeps engagement signals healthy.

That's also why the warning line is stricter. A drop on transactional mail usually points to a broken setup, not a content issue: something is wrong at the SPF, DKIM, or DMARC layer, or your sending IP is in trouble. 100% inbox delivery isn't a realistic target even here, so investigate as soon as you slip below the benchmark.

What is a good inbox placement rate by mailbox provider?

Inbox placement varies a lot by provider, and a single average hides it. The 2025 global breakdown put Gmail at 89.8%, Yahoo/AOL at 87.3%, Apple Mail at 82.0%, and Microsoft/Outlook at 77.4%. Outlook trails the others by more than 10 points.

That spread is why an overall number can mislead you. A program reporting 87% inbox placement might be inboxing at 95% on Gmail and 65% on Outlook. The headline number looks fine, while every business contact on an Outlook or Microsoft 365 domain misses your mail, and those contacts are often your most valuable segment.

LB Blair, an email deliverability consultant who works with SendX, makes the same point: basic delivery, open, and click rates don't cut it anymore, and you need to see those metrics by mailbox provider. A blended average can look healthy while one provider sends everything to spam.

The way to get that per-provider view is an inbox placement test, also called a seed test. With SendX's Inbox Testing add-on, you send your campaign to a set of monitored test addresses at the major mailbox providers before it goes to your list. The report shows how many copies landed in the inbox, how many went to spam, and how many went missing, so you can see a problem at one provider instead of guessing from open rates. It also checks your email against spam filters before sending, so you can fix the trigger and retest before your subscribers ever see the campaign.

What is a good spam complaint rate?

Spam complaints are one of the fastest ways to lose inbox placement, so they deserve their own benchmark. Every time a subscriber clicks "report spam," the mailbox provider counts it against you, and enough of those clicks move future emails from the inbox to the spam folder.

Keep your spam complaint rate below 0.1%. Google's email sender guidelines set a target under 0.1% and name 0.3% as the level where filtering kicks in. Once you cross 0.3%, inbox placement drops fast, and no other benchmark in this guide matters until you fix it.

Gmail and Yahoo both enforce these thresholds, and they apply whether you send marketing or transactional email. Complaints damage your sender reputation faster than almost anything else.

LB suggests reading the percentages as people. A 0.1% rate is "one person at a thousand" marking you as spam, and 0.3% is 3 people in every thousand you send to. Put that way, 0.1% is a tight ceiling, not a generous allowance. The practical target is to stay well below it, not just under it, by keeping your list clean and making unsubscribing easy enough that people use it instead of the spam button.

How do I improve a below-benchmark deliverability rate?

If your rate is under benchmark, fix it in this order: clean your list, confirm authentication, warm up new infrastructure, and segment by engagement. Many problems that look like content problems turn out to be list problems.

Start with list hygiene. Remove hard bounces, suppress addresses that keep failing, and cut subscribers who haven't engaged in months. Every send to a dead address tells mailbox providers your list isn't maintained.

Next, confirm SPF, DKIM, and DMARC are all in place and aligned. Gmail and Yahoo require them from bulk senders, and a misconfiguration caps your inbox placement no matter what else you fix. If this is your first time setting them up, our SPF, DKIM and DMARC setup guide walks through each record.

Then work through the rest:

• Warm up new IPs and domains slowly. Start with low volume and increase it in steady steps while you watch bounce rates.

• Segment by engagement. Send to your most active contacts first, then expand to less active segments once your reputation holds.

• Monitor inbox placement per provider. Overall delivery can look fine while one provider filters you.

• Watch your spam rate in Google Postmaster Tools. You want to catch a climb well before it reaches 0.3%.

If your mail is already landing in junk, our guide to why emails go to spam goes deeper on each fix.

How do I measure my own deliverability rate?

Start with 2 different numbers.

1. Delivery rate

This tells you how many emails were successfully accepted by receiving mail servers.

Calculate it like this:

Emails delivered ÷ emails sent × 100

For example, if you send 10,000 emails and 9,800 are delivered, your delivery rate is 98%.

You usually do not need to calculate this yourself. Your email platform should report the delivery rate for every campaign.

2. Inbox placement

This tells you where those delivered emails actually landed, such as the inbox or the spam folder.

Mailbox providers generally do not report this information back to senders. To estimate inbox placement, you need to run an inbox placement test, also called a seed test.

Because these numbers tell you different things, check them on different schedules:

• Check delivery rate after every campaign. A sudden drop can be an early sign that something is wrong.

• Run an inbox placement test at least once a quarter.

• Run another test if your performance changes noticeably or you make a major change to your sending setup.

It also helps to test when everything is working well. That gives you a baseline to compare against later.

Inbox placement becomes much more useful when you can see how it changes over time. That ongoing visibility is an important part of maintaining high deliverability.

How SendX helps you track both numbers

Following the schedule above usually means juggling tools. Your email platform shows delivery rate, a separate seed-testing service shows inbox placement, and you piece the 2 together by hand after every campaign.

SendX is an email marketing platform for growing businesses. You build your list with forms and landing pages, send newsletters and campaigns, and run automated email sequences from one account. Deliverability tools are built into the same place you send from, so you don't need a separate service to check both numbers.

After each campaign, the AI Deliverability add-on gives you a report with your delivery rate, a health score, and a list of critical issues to fix. That covers the "check delivery rate after every campaign" step without exporting anything. When it's time for your quarterly test, or when a number moves, Inbox Testing shows where the campaign landed at each major provider, so your baseline lives next to your campaigns.

SendX also protects both numbers in the background. Hard bounces are suppressed automatically, so you are not continuing to send to addresses that have already failed and dragging your delivery rate down. Unsubscribe links can run on your own verified domain, which gives people an easier exit than the spam button and keeps your complaint rate low.

The result is one place to send your email, see whether it arrived, and see where it landed. If you're ready to check both numbers on your own campaigns, start a free SendX trial.
