The Best Day of the Week to Email Past Clients

The Tuesday-Thursday gospel has been circulating in email marketing circles for years. If you’ve read any email advice, you’ve heard it. But advice written for SaaS newsletters isn’t the same as advice for real estate agents emailing past clients who bought a house two years ago.

Let’s look at what actually matters — and when the day of week question is the wrong one to be asking.

Why Tuesday and Thursday Became the Default Answer

Most send-day studies come from platforms like Mailchimp and Campaign Monitor that aggregate data across millions of sends in B2B and e-commerce. Their finding: Tuesday and Thursday outperform Monday, Wednesday, Friday, and the weekend.

The logic holds at a surface level. Monday mornings are inbox chaos — people are catching up and your newsletter competes with everything that piled up over the weekend. Friday afternoons, people are mentally checked out. Weekends are family time. That leaves Tuesday through Thursday as the clear window.

For a past-client newsletter from a real estate agent, the same logic mostly applies. Your readers aren’t expecting your newsletter the way they’d expect a tracking email from a package. They’re checking email between other tasks, and mid-week is when they’re most receptive to something non-urgent.

The Case Against Blindly Following the Benchmark

Here’s the problem with applying industry benchmarks to your list: your list is probably 200 to 2,000 people who all know you personally.

A benchmark pulled from millions of sends includes cold lists, e-commerce newsletters, B2B drip campaigns, and promotional blasts from companies the subscribers barely remember signing up for. The engagement dynamics are completely different from an agent who closed with these people and has a genuine relationship with them.

That matters because familiarity overrides timing. A past client who remembers you and trusts you will open your email on a Wednesday just as readily as a Tuesday. The relationship is doing more work than the calendar.

What Day-of-Week Research Looks Like for Relationship Newsletters

Some nuance gets lost in aggregate studies. A few things worth noting:

Monday mornings underperform for everyone. This one is reliable. People are triaging a full inbox and your newsletter is easy to defer or miss entirely. If you’re currently sending Monday morning, test a shift to Tuesday or Wednesday.

Fridays are weaker for action, better for reads. If your goal is someone clicking through to your website or replying, Friday underperforms. If you just want them to read a market update over lunch, it’s fine. Most agent newsletters want replies and clicks, so mid-week edges out Friday.

Sunday evenings are more popular than they used to be. Some research on consumer newsletters (rather than B2B) shows Sunday evening sends — when people are winding down and thinking about the week ahead — getting solid open rates. Real estate is a consumer business. If your audience skews toward families who are more reachable on Sunday evenings, it’s worth a test.

Consistency matters more than optimization. If your newsletter lands on the second Tuesday of every month without fail, your readers start to expect it. That expectation is worth more than any A/B test finding. Pick a day and stick with it.

How to Find Your Own List’s Best Day

You don’t need a huge list to run a useful test. Here’s a simple approach:

1. Split your list roughly in half (most email platforms do this automatically with A/B tools).
2. Send the same newsletter — identical content and subject line — on two different days in the same week.
3. Wait 48 hours, then compare open rates. Ignore Apple Mail Privacy Protection inflated opens; look at click rates and reply rates instead.
4. Repeat once or twice before drawing conclusions.

This takes about three months of sends to get a signal worth acting on. That’s a good investment if you’re serious about optimizing. For most agents just getting started, it’s not where to spend your energy first.

Which Day to Start With If You’re Not Sure

If you’re launching a new newsletter and want a sensible default, Tuesday or Thursday morning is the right starting point. Here’s the reasoning specific to real estate past clients:

Tuesday sits far enough from the Monday chaos that inboxes are manageable, but early enough in the week that people are still in planning mode. If your newsletter has anything actionable — a market update, a home maintenance tip, a reminder — readers are in the right mindset to do something with it.

Thursday has a slight advantage for service-type businesses because it catches people before they mentally shift into weekend mode. If your newsletter is more lifestyle-driven or personal, Thursday can feel warmer.

Avoid Wednesday if your newsletter content is market-focused. Wednesday is peak “list inbox” day for many professionals, and you’ll be competing with more noise.

Does Day of Week Really Move the Needle?

Honestly? Less than you’d think.

Once you’ve been sending consistently for six months, your open rate stabilizes and the day-of-week effect becomes marginal. The research showing Tuesday as the best day is often measuring differences of a few percentage points. Content quality, subject line, and list health all dwarf that effect.

The best thing you can do for your newsletter open rate is write something worth reading every time. A newsletter your past clients actually enjoy gets opened whenever it arrives.

For a systematic approach to staying in touch beyond timing, the real estate email marketing guide covers the full picture. And if you’re still figuring out what to say each month, past-client newsletter ideas will give you a content menu that keeps your list engaged long-term.

Pick Tuesday or Thursday, send consistently, write good stuff. That’s the whole strategy.
