Open rate drop
Why are my email open and click rates dropping?
Open rates drop for three reasons, and only one of them is your content.

07 – Open & click rate drop FAQ
Falling engagement is both a symptom and a cause
Gmail, Microsoft, and Yahoo score you per recipient based on how people interact with your mail. When engagement drops, they move more of your sends to Spam or Promotions, which lowers engagement further, which tightens the filtering.
Opens slid for months, then clicks followed.
The classic filtering curve, not a creative one.
Gmail dropped, other providers didn’t.
Provider-specific filtering.
Your list grew, but revenue per send fell.
The new volume is diluting, not compounding.
Frequency went up, totals stayed flat.
Spending reputation to stand still.
Open rate looks fine, clicks don’t
Automated opens are masking the decline.
Re-engagement campaigns underperform
Already filtered, so the win-back never arrives.
Any of these could be quietly killing your deliverability
Each of these causes points to the same outcome: the inbox stops trusting you, and your campaigns stop performing. The tricky part: several can be true at once, and the wrong fix makes it worse. That’s why a proper diagnosis with a relevant implementation order matters.
01
No sunset policy or segmentation
Contacts dormant for 6–12 months still get every send; your best subscribers subsidize your worst.
02
Frequency outrunning interest
More campaigns increase fatigue, deletes, and complaints faster than they increase revenue.
03
Mail landing in Spam or Promotions
Opens can’t happen where nobody looks; placement problems look like engagement problems.
04
Weak acquisition, mismatched promise
Contests and bought lists bring people who never wanted this; those who expected something else just stop.
05
Automated opens hide the decline
Machine-fired pixels keep the dashboard green while human attention drops.
06
Broken or hidden unsubscribe
Hard opt-out turns unsubscribes into spam complaints. One-click is mandatory since February 2024.
07
Authentication or infrastructure gaps
Missing DKIM alignment or an unwarmed domain suppresses placement before engagement is measured.
08
Re-engagement at full volume
A win-back to a large, dormant segment consolidates all negative signals into a single send.
09
No one-click unsubscribe
Since 2024, it’s mandatory — miss it and Gmail & Yahoo throttle you outright.
10
Domain spoofed or compromised
Abuse sent under your name destroys the reputation you spent years building.

“MailSoar helped us stop the bleeding quickly, then restructure our email marketing, sales, and product approach. Problem solved!”
“Pierre and his team from Mailsoar have helped our company improve our email deliverability metrics to ensure that we get as many of our emails in our customers inbox as possible. Prior to his team working with us we saw a large number of emails going into spam, junk, or for the case of gmail, promotions/social. . As an online marketplace, emails are a crucial component to our supply and demand components interacting efficiently. This has helped improve that efficiency.”
“MailSoar had a huge impact on our business and I highly recommend them. They helped us grow our open rate from ~10% to almost 50% for our eCommerce store by optimizing our email strategy and implementing various deliverability tactics. We have been using their service for a few months now, and I couldn't be happier with their knowledge, expertise, and great communication.”
“We came to MailSoar to help with our deliverability. We were so happy with their work on this, that we have continued to work with them for the past year to monitor our deliverability and to act as trusted consultants for a very important email marketing program. Our email deliverability metrics have drastically improved since starting with MailSoar. As a result of this email performance and revenue improved drastically.”
“We partnered with MailSoar to improve our email deliverability and sender reputation. They helped us set up a new dedicated subdomain to isolate our transactional/marketing mail flow from our primary domain, and worked with us to bring our DMARC compliance up to 97%. Since implementing MailSoar's recommendations, our email delivery rate has climbed to 99.6%. Just as importantly, the sender reputation for both humanx.co and mail.humanx.co went from "Bad" to "High". A great turnaround that's had a real impact on our ability to reliably reach our audience.”
“From time to time, we have had issues with our deliverability, and every time MailSoar has helped us resolve the problem and put in practices that have kept us out of trouble. We went from a place of having consistent issues with deliverability a couple of years ago to a place now where we rarely have them. And even when we do, these guys are the absolute experts in what is going on in the industry and know how to get deliverability issues resolved instantly. Cannot recommend them highly enough.”
“We are facing email deliverability issues, and Mailsoar gave us great free advice to start, and then we went forward with an email audit from them that set us up to fix the issues we have.
In just over a week, we received an audit and an action plan that we are implementing to recover our email deliverability.
We are highly confident that the plan will work and be successful.”
“I was running a complex, large-scale email campaign (...) and unfortunately, we discovered that poor hygiene and other technical issues meant almost all of our emails were going to spam.
The MailSoar team was so proactive, creative, and professional. I knew I didn't just have a vendor: I had a true partner whom I could trust completely, and who cared about the success of this project as much as I did. MailSoar saved my email campaign contract. I absolutely could not have done this without them.”
“Pierre understood the expectations of the job, was able to properly articulate the challenges we faced, and did a great job communicating with us through every phase of the project until it was completed. Most importantly he successfully completed the project in a timely manner. I would highly recommend Pierre.”

Is your situation slightly different?
A drop in engagement often overlaps with these related deliverability challenges. Explore the one that fits your situation best.
My emails land in Spam or Promotions
SPAM & INBOX PLACEMENT
Diagnose why mailbox providers filter you out and the levers that move you back to the inbox.
In most cases, because fewer people are seeing your mail, not because your content has gotten worse. Providers move mail from an audience that has stopped engaging to Promotions, then to spam, so the opportunity to open disappears before the subject line matters. The other two common causes are list decay and rising frequency that outpaces audience interest. Content is usually the third suspect, not the first.
Is a falling open rate really a deliverability problem?
Often, yes — but not always. If opens fall evenly across every provider and clicks hold steady relative to opens, you’re likely looking at creative, offer or timing. If the decline is concentrated at one provider, or clicks fall faster than opens, the mail is being filtered. Seed testing and provider-split reporting tell those apart in a day; guessing costs months.
Are open rates still worth tracking after Apple MPP?
Yes, as a deliverability signal rather than an engagement KPI. Since iOS 15 in September 2021 — and now non-human interaction across all providers — machine-fired pixels can hide a genuine decline for months. But a unique open rate below ~20%, or a fall from 40% to 20%, usually means you’ve lost inbox placement at a major provider. The trend matters more than the number.
What is a good email open rate in 2026?
Benchmarks are close to useless here. What matters is your own trend line, split by provider and by subscriber recency. A 22% open rate, down from 34% over two quarters, is a problem; a stable 18% on a well-segmented B2B list is not. Compare yourself to your last six months, not to an industry average measuring a different audience.
How long does it take for email engagement to recover?
Placement usually stabilizes within 2 to 6 weeks of changing what you send and to whom. Engagement-based reputation at Gmail takes longer — about 3 months of consistent, positive sending before the scoring fully reflects the new behavior. Recovery is not linear: expect initial improvements in your most engaged segments, then a gradual widening.
Do re-engagement campaigns actually work?
They can, but they’re the most commonly mishandled tactic in email. Sent as one large blast to every dormant contact, a win-back concentrates deletes, complaints, and non-opens into a single send and can push you from filtered to blacklisted. Done properly: small controlled waves, a clear opt-out, and a hard suppression rule for non-responders. They recover a meaningful slice and cleanly retire the rest.
Stop the engagement spiral before it becomes a spam problem
Our consultants will tell you where your mail is actually landing.
MailSoar helps companies facing falling open and click rates by separating measurement effects (privacy protection, tracking) from real filtering problems, checking inbox placement and sender reputation, and fixing what actually holds engagement back. Swile’s open rate went from 20% to 35%.
