If you’re a pastor or nonprofit director who opened your email platform this month, squinted at the dashboard, and thought “wait, did our open rate just fall off a cliff?” — you’re not imagining it, and you’re not alone.
A lot of small ministries and nonprofits have watched their newsletter open rates slide through late 2025 and into 2026. The good news is most of the drop isn’t because your content got worse or your people stopped caring. It’s because the email inbox itself changed around you. The better news is there are three or four small habits that will get your numbers moving back in the right direction — none of them require a marketing degree or a new platform.
The short version
- Gmail and Apple Mail tightened their sender rules in late 2023 and again in 2025. If your church or nonprofit hasn’t updated its sending setup since then, you’re quietly being filtered.
- “Open rate” itself is a shakier number than it used to be because Apple’s Mail Privacy Protection pre-loads images. Don’t panic over the percentage — watch the trend and the clicks.
- Three habits move the needle the most for small senders: authenticating your domain, writing subject lines like a human, and pruning inactive subscribers instead of letting them drag you down.
- You can make real progress in about 90 minutes, spread across a couple of weeks. No agency required.
What actually changed
Two things happened, and they both work against small senders who haven’t been paying attention.
First, Gmail and Yahoo rolled out new sender requirements in February 2024, and Apple quietly followed with stricter filtering in 2025. If you send more than a handful of emails a week — and most ministry newsletters do, if you count event announcements — you’re expected to authenticate your domain with three things called SPF, DKIM, and DMARC. Those are just small records that live in your domain settings and tell Gmail “yes, this email really did come from us.” If any of them is missing or misconfigured, Gmail increasingly quiet-rejects your newsletter into the Promotions tab or the spam folder. People don’t see it. Your open rate tanks.
Second, Apple Mail Privacy Protection (rolled out in 2021, but now used by a larger share of your readers than ever) pre-loads the tracking pixel that email platforms use to count opens. That makes every Apple Mail reader look like they “opened” the email the moment it arrived, whether they actually read it or not. So your open rate number became less reliable as a measure of real reader attention — even while other parts of your list got quieter for legitimate reasons.
Put those together and you get the pattern a lot of church communicators are seeing: a list that seems fine on the surface, an open rate that used to be 40% and is now 22%, and a gut feeling that something is broken.
Habit 1: Authenticate your domain (and check it every quarter)
If you take only one thing from this post, take this: go to mxtoolbox.com, type your sending domain into the “SuperTool” box, and run an SPF lookup, a DMARC lookup, and a DKIM lookup. It takes about two minutes.
SPF, DKIM, and DMARC are the three little signatures that prove your email is really from you. If any of them comes back with an error or “not found,” your newsletter is being treated as suspicious by the big inbox providers, and you’re losing opens to the spam folder without even knowing it.
The fix is usually not hard, but it does require adding a few DNS records. If you use Mailchimp, Constant Contact, Flodesk, or MailerLite, they all have step-by-step guides for authenticating the specific domain you send from — search their help docs for “domain authentication” and follow the walkthrough. If your church uses a denomination-provided domain or something your web volunteer set up years ago, you may need to ask your platform support to help. This is a task worth escalating; the deliverability improvement is real and immediate.
A quick tip: authenticate the same domain your church website lives on (yourchurch.org), not a generic one like mail.yourchurch.org or something from your email platform. Gmail trusts matching domains more.
Habit 2: Write subject lines like a human you’d want to hear from
Subject lines are doing more work than ever, because Gmail’s Promotions tab collapses your email into a single line of preview text and you’re fighting for attention against twelve coupon codes. Two things help here, and they cost nothing.
First, drop the institutional voice. “April 2026 Newsletter — St. Mark’s Edition” is a subject line that nobody clicks. “One thing I’ve been turning over this week” or “A small update from the rec hall kitchen” gets opened because it sounds like a person wrote it. You don’t have to be clever or cute — you just have to sound human. Imagine you were writing a subject line to one specific person in your congregation. What would you actually type?
Second, stop asking for things in the subject line. “Please donate,” “Register now,” “Help us reach our goal” — these read to Gmail’s filters, and to tired readers, as marketing. Save the ask for the body of the email. Use the subject line to create curiosity or to name something specific that happened.
A useful rule: if your subject line could appear on any church’s newsletter this month without changing a word, rewrite it. Specificity is your friend. “Holy Week 2026” is generic. “What I learned watching you all on Palm Sunday” is a person talking.
Habit 3: Prune inactive subscribers (yes, really)
This is the one nobody wants to do, and it’s the one that helps the most.
Here’s the math: Gmail watches the percentage of your recipients who open and engage with your emails versus the percentage who ignore them. If you have 800 subscribers and 300 of them haven’t opened anything in a year, those 300 are actively dragging down your sender reputation every time you send. Gmail sees the non-engagement and says “this sender probably isn’t wanted, let’s filter them harder.” Your 500 real readers start seeing your emails in Promotions or spam because of the 300 who stopped caring.
The counterintuitive fix: remove the inactive subscribers. Most email platforms let you filter by “no opens in the last 180 days” or similar. Export that list, send them one final “we’d love to stay in touch — click here if you want to keep hearing from us” email, and then after two weeks, remove everyone who didn’t click.
Your list will shrink. Your heart will sink a little. And then your next newsletter will land in more inboxes than it has in a year, because the people still on your list are the ones who actually want to be there.
If you can’t bring yourself to delete anyone (I get it — we’re in ministry, every person matters), at least move inactive subscribers to a separate list and send to them less often. Monthly instead of weekly. Or only for the two or three emails a year that really matter. Gmail will reward you for respecting your readers’ attention.
What to watch instead of the open rate
Since open rates got noisy in 2025, track these instead:
- Click rate. Did people click any link? This one is still honest.
- Reply rate. Did anyone write back? For a 500-person ministry list, even one real reply per newsletter is a green light.
- Unsubscribe rate per send. If this creeps above half a percent, your content or cadence needs a look.
- Spam complaint rate. Anything above 0.1% is a red flag — Gmail will start filtering you harder.
Your email platform shows all of these. You don’t need a new tool.
A small next step
This week, pick one thing: go to mxtoolbox.com and run your domain through the SPF / DKIM / DMARC checks. If any of them fails, that’s your next project — and it’s probably the single highest-impact fix you can make to your email program right now. If they all pass, congratulations — move on to pruning inactive subscribers next.
You don’t have to fix everything at once. Fifteen minutes with mxtoolbox is a real start.
