The 10 surprising (and scary!) ways you lose new email subscribers

Here are the sneaky leak points that catch so many email marketers out…

As you read, ask yourself – are you doing any of these right now? And be honest!

Four reasons new email subscribers feel like they got ghosted 👻

Getting ghosted never feels good – and it’s not forgiven easily. So make sure you’re not accidentally ghosting your new email subscribers…

1. No email gets sent at all

  • You don’t send an email after optin
    You either never made a welcome sequence, or your automated process is broken. When someone gives you their email and gets zero reply, it’s a slap in the face. They feel ignored and ghosted. New email subscriber lost.

2. Email is sent but gets blocked or placed in the spam folder

  • Incomplete or missing email authentication
    Mailbox providers put suspicious-looking emails in the spam folder (or worse, ddon’teliver them at all!)
    If your emails don’t wear their proper domain authentication (like SPF/DKIM/DMARC), they will never reach the inbox, or will head straight to spam. New email subscriber lost.

Here’s some help to check your email authentication quickly

3. Disguised as a mystery sender

  • Using from “Gary”, “Beth”, or any unclear sender name
    When your email shows up with a sender name the recipient recognises, it’s likely going to get deleted or ignored. New email subscriber lost.

This is such an easy win to improve. We always use Kay Peacey – Slick Business as our sender name.

4. Delayed first email

  • You wait hours or days before emailing New leads are hot, but if you don’t show up quickly, they forget you, or think you don’t care. By the time your message arrives, it’s unwanted and often reported as spam. New email subscriber lost.

Four reasons new email subscribers don’t like what they see, and leave 😵

Our inbox space is precious – so make sure what you send in the first days is not unintentionally annoying or alienating your new email subscribers…

5. Unreadable, ugly first email

  • Garish, crowded hard to read screen, all images, or a wall of text
    If your new subscriber opens your first email and it’s a bad experience – especially if it looks awful on mobile – they’ll unsubscribe and not come back. New email subscriber lost.

6. Email deluge!

  • Too many emails within hours of signing up
    Bombarding someone right away feels overwhelming and spammy. You’ll get unsubscribes or even spam reports fast. New email subscriber lost.

7. Hard sell in the first email

  • Going straight in with a determined pitch
    If your very first email is trying to sell them something, people hit unsubscribe or mark you as spam. It feels pushy and unwelcome. New email subscriber lost.

8. Dropping into mid-conversation

  • Your first email presumes they know your jargon or backstory
    Starting in the middle of a topic confuses people, makes them feel left out, and pushes them to unsubscribe. New email subscriber lost.

9. Bland, boring, personality-free emails

  • Your welcome email is generic or “too AI”
    If it feels inhuman, irrelevant, or unbranded, most subscribers tune out. They may not bother unsubscribing, but they’re unlikely to engage, and may just send you straight to the trash can. New email subscriber lost.

10. Old, irrelevant welcome messaging

  • Dusty sequence doesn’t match current offers/branding
    If your first emails haven’t been updated in ages, they won’t make sense to new subscribers as they arrive. Result: loss of interest, no engagement, or silent zombies on your list. New email subscriber lost.
