1) Use the right “From” email address

✅ Best practice

Send emails from an address that matches your business, like:

hello@yourgymname.com (or anything on your gym’s domain)

❌ Avoid

  • Sending from gmail.com or yahoo.com (example: mygym@gmail.com)

  • Typing a random “From” email that doesn’t match your gym domain

Tip (common setup)

If your Grow account already has a business email/domain set up, use that in your emails.


2) Don’t “blast” emails all at once (use batch sending)

Sending too many emails at once can look like spam. Instead, send in smaller groups.

✅ Best practice: Batch Schedule / Drip mode

When sending an email campaign, choose:

  • Batch Schedule (sometimes called “Batch send” or “Drip”)

Recommended settings:

  • Send in small batches (example: 25–50 at a time)

  • Repeat every 1 hour (or similar)

This helps email providers trust your sending.


3) Keep your sender name consistent

Pick one sender name and stick with it every time, like:

  • “Your Gym Name”

    or

  • “Coach Sam at Your Gym”

❌ Avoid switching between:

  • Gym Name

  • Owner First Name

  • Owner Full Name

    Changing often can hurt trust.


4) Write emails people want to open

Email providers watch what people do with your emails.

Good signs:

  • Opens

  • Clicks

  • Replies

  • People keep your email (don’t delete right away)

Bad signs:

  • People ignore your emails

  • Unsubscribes spike

  • People mark you as spam

Simple rule: Send helpful content your members actually care about.


5) Use a clear subject line (no tricks)

✅ Good subject lines:

  • “New class times this week”

  • “Free intro session reminder”

  • “3 tips to stay consistent this month”

❌ Avoid:

  • ALL CAPS, lots of !!!!

  • “RE: Your Order” (if it’s not true)

  • Super spammy words like “BUY NOW!!!” or “FREE!!!” over and ove


6) Build simple emails (text-first)

✅ Best practice

Keep emails mostly text, like a real message. Add 1–2 helpful links.

❌ Avoid

  • Emails that are mostly images

  • Too many buttons, banners, and links

  • Link shorteners (like bit.ly)

If images don’t load, your email should still make sense.


7) Always include an unsubscribe option

People should be able to opt out easily. If they can’t unsubscribe, they’re more likely to hit “Mark as spam” (which hurts deliverability).


8) Keep your list healthy (send to the right people)

Do this:

  • Only email people who asked to hear from you

  • Remove inactive contacts (example: no opens/clicks in 90+ days)

  • Protect forms with reCAPTCHA or double opt-in to block bots


9) Testing tip (avoid “internal mail” issues)

If you send an email from and to the same domain (example: you send to you@yourgym.com from you@yourgym.com), it may go to spam.

Best way to test

Send test emails to a personal inbox like:

  • Gmail

  • Outlook


Quick Checklist (Most Important)

If your emails are going to spam, start here:

  • I’m sending from a business domain email (not Gmail/Yahoo)

  • I’m using Batch Schedule / drip (not blasting all at once)

  • My From Name stays the same every time

  • My email is mostly text, not image-heavy

  • I include an unsubscribe option

  • I’m sending to a clean list (not old/unengaged contacts)


Common Problems

“My emails used to work, now they don’t.”

Email providers change rules often. Using batch sending + a business domain usually fixes most problems.

“My test email went to spam.”

Try sending the test to a Gmail address. Internal domain testing can be unreliable.

“People aren’t opening emails.”

Send fewer emails, make subject lines clearer, and message smaller groups with more relevant content.
