HEY! Did you remember the Tiger King documentary during COVID!? What a throwback - I just watched it again - so good! So anyway, hello all you cool cats and marketers, before we dig in - two really good things that happened:
1. Ran my second cohort of the Email Design Masterclass, and the feedback was insane. People are walking away and immediately rebuilding their emails, which is exactly the point. If you haven't been to one yet, you NEED to.
2. And we've hit 100 learners in the Email Deliverability Certification Programme. People are loving it and, more importantly, actually learning SO much!! Enrolments close at the end of the month if you fancy joining them.
Let's go - lot's you NEED to know:
Can sending too little emails hurt deliverability?
One email a month is NOT enough now
Gmail has a built-in, automated feature that prompts users to unsubscribe from newsletters and promotional emails they haven't opened in over 30 days.
HOW CRAZY IS THAT!?
Personally, I think it's a stupid feature (more on that soon).
Not sending enough is a deliverability problem too.
Positive signals on one side & negative signals on the other
Inbox placement isn't a pass/fail gate; it's really which way those scales are tipping.
All the standard advice only tackles the negative side. But you can lose that balance just as easily by failing to generate enough positive signal
Now this advice is NOT telling you to send to everyone and keep sending but...
So if you're sending monthly or you stop and start or go quiet for six weeks, then come back with a big send, and you're doing a cold send to a warm list.
This will HURT your sender reputation
There's so much you need to know about this topic, so I've broken down what you need to know and do below.
What is BIMI, How to Get It, What It Costs, and Does it Help Email Deliverability?
BIMI stands for Brand Indicators for Message Identification
It's what puts your verified brand logo next to your sender name in the inbox, before anyone opens anything.
What it means in practice:
Two certificate types. VMC needs a registered trademark and gets you the logo plus the blue verified checkmark in Gmail. CMC needs no trademark (just 12 months of commercial logo use) but no checkmark, and Apple Mail doesn't support it yet.
What it costs:
VMC is roughly £1,100–£1,400 a year. CMC around £770-£990. Annual renewal, every year. No trademark yet? That's another 6-12 months and a few hundred quid on top.
Does it help deliverability?
Not directly. There's no signal telling providers "this sender has BIMI, put them in Primary." Placement is still engagement, reputation, list hygiene, authentication and relevance.
Grab the hex codes from your last email and drop them into the WebAIM Contrast Checker.
You can test everything: body copy, headlines, button background against button text, links, footer text, even images with text sitting on top of them.
Around 8% of men have some form of colour blindness. Add low vision, older readers, and anyone squinting at their phone in sunlight, and that's a big chunk of your list struggling to read you.
And if you've got EU subscribers, the European Accessibility Act made this a legal requirement back in June 2025.
There's a bit of a wait to work with me at the moment, so if you've got something on the horizon, now's the time to get in touch.
Whether it's a problem you can't crack, an opportunity you can see but can't unlock, a workshop for the team, an audit, or a full email transformation - it's always better to talk early.
And if you're building 2027 budgets right now (I know a lot of you are), that's exactly the moment to get me in. Easier to get the money signed off when you know what you're asking for.

Send consistently, check your contrast, and stop letting a logo distract you from the fundamentals.
