How to keep your salon marketing emails out of spam

Salon and spa owners can keep their marketing emails out of spam by using a custom domain, setting up SPF, DKIM, and DMARC, starting small, experimenting, and keeping lists clean.

Email deliverability isn't luck and it isn't a mystery. It's a short list of technical basics plus one behavioral rule, and once it's set up, it mostly stays set up.

Why your salon marketing emails end up in spam

Most salon and spa marketing emails end up in spam because their system isn't authenticated or their emails aren't engaging.

Mailbox providers like Gmail and Yahoo are asking two questions about every email you send: "Are you really who you say you are?" and "Do people want this?" Most salons fail the second question, not the first. You can have perfect technical setup and still land in spam if you email 800 people who haven't heard from you since 2022 and nobody opens it. Filters read that silence as a verdict.

So, how can you keep your salon and spa marketing emails out of spam? Let's dig in.

Use a custom domain

Using a custom domain to send salon marketing emails is the single highest-impact fix on this list. Do it first.

You shouldn't use free email addresses (like yoursalon@gmail.com) to send your emails because they can't be authenticated the way a real domain can. Providers treat them as suspicious for bulk sending.

If you own a website then you already own a domain. So instead, send them from hello@yoursalon.com. You can set this up with your website host for free or small monthly cost. Trust me, it's worth it!

Mangomint makes this very simple. You connect your domain in your settings, and then it walks you through how to set a custom sender address for every campaign and flow.

Set up your DNS records

DNS records, like SPF, DKIM, and DMARC, are required email authentication methods for anyone sending in volume. Basically, they legitimize your email domain. Without them in place, mailbox providers will find your emails phishy and send them to spam.

• SPF is a list of who's allowed to send email using your domain name.

• DKIM is a tamper seal that proves the message wasn't altered in transit.

• DMARC tells mailbox providers what to do when something fails the first two checks.

Any email platform or salon software with built-in campaigns will walk you through how to set up your DNS records, and it's usually copying three lines into your domain settings. It takes about 20 minutes.

Mangomint's custom domain setup auto-generates and displays the exact DNS records needed, so you're pasting values into your domain host rather than configuring anything yourself.

Start with a small list

This is the mistake that sinks more salons than any technical issue.

If you haven't emailed in two years and you send to all 900 contacts at once, low engagement tells the filters nobody wants your mail. One bad send can affect where your next several land.

Instead, send to your most engaged clients first. Start with anyone who's been in within the last 90 days. Let the opens and clicks accumulate for a week or two, then expand to the next tier, then the rest. You're building evidence that people want to hear from you before you ask the filters to take your word for it.

The same logic applies to a brand new list. Grow into it. Don't announce yourself to everyone on day one.

Experiment with subject lines

Don't use "BIG SALE" or anything in all caps with exclamation points as a subject line because it reads as promotional to filters and to humans. So does anything that sounds like it was written by AI. Filters have gotten good at detecting the flat, over-polished register, and so have your clients.

Write like you're texting someone you like. Aim for something that sounds like the beginning of a conversation.

A few subject lines to avoid:

• "October Newsletter"

• "Fall Hair Care Tips"

• "Don't Miss Our Biggest Sale of the Year!!!"

The first two are accurate and boring. The third is trying too hard and trips filters.

Try A/B testing them. Most platforms will let you send two versions to a slice of your list and roll out the winner. You'll learn more about your specific clients in 3 email tests than in any article, including this one.

Aim for industry standards

"Don't be spammy" isn't actionable here, so here are industry-specific email marketing metrics you should aim for:

• Spam complaint rate: Gmail and Yahoo start penalizing senders above 0.3%. Google recommends staying under 0.1%. That's 1 complaint per 1,000 emails.

• Unsubscribe rate: the average in beauty is about 0.3%. If you're in that range, you're normal. Unsubscribes are not a failure, they're list hygiene happening on its own.

• Click-through rate: the salon and spa benchmark runs 4-6%.

If your numbers aren't meeting industry standard, the way out is consistency. Providers restore standing after spam rates stay below the threshold for several consecutive days. It's recoverable! It's just slow, which is a good reason not to get there.

Keep your list clean

Every six months, look at who hasn't opened or clicked anything in a year. Send them one honest re-engagement email. Something like: "It's been a while. Still want to hear from me?" The ones who click stay. The rest, remove.

This feels backwards when you've worked to build a list. But a list of 300 people who read your emails outperforms a list of 900 where 600 never look, both in bookings and in deliverability.

Dead weight actively drags down the live contacts. Salon and spa booking software like Mangomint can automatically tell you who hasn't been in for two years, which is a good qualifier for who's unengaged and should be removed.

TL;DR

If you only do four things to keep your salon and spa marketing emails out of spam:

1. Send from your own domain, not Gmail

2. Set up SPF, DKIM, and DMARC once

3. Warm up a cold list before you start sending a lot

4. Email consistently enough that your clients recognize your name

That last one is the one people skip, and it's doing more work than the other three combined. Filters reward senders whose mail gets opened. The most reliable way to get opened is to be someone your clients expect to hear from. And if you're using Mangomint for your salon, most of this list (custom domain, authentication, list hygiene, personalization) is either built in or easily set up.
