Welcome back to Icon City Office Hours! I’m Aigner Ellis, here to talk about the behind-the-scenes hiccups that keep us, as entrepreneurs, on our toes. And today’s story? It’s all about email. Yes—email. That thing we all take for granted until it suddenly stops working.
The Issue
A client recently came to me with a head-scratcher. Their email campaign to customers was met with a flood of bounce-back notifications, mainly from Gmail. For a minute, we all thought it was some classic Monday morning nonsense. But no. The messages weren’t reaching inboxes and were instead met with errors linked to something called DKIM and SPF.
If you’re like me, your first thought might’ve been, “Who’s DKIM, and why are they messing with my client’s emails?” But after some digging, it became clear that this wasn’t just a random glitch—it was Google's way of saying, "Play by the rules, or you’ll never reach our users again."
What We Learned About DKIM (and SPF)
Here’s the deal with DKIM (DomainKeys Identified Mail): it’s an email authentication method. Basically, it uses digital signatures to verify the authenticity of an email. Think of it as a bouncer for inboxes, checking credentials at the door.
Here’s how it works:
The sender’s email system generates private keys for a domain and digitally signs parts of the outgoing email.
When the email arrives, the recipient’s mailbox provider (like Gmail) looks for a public key stored in the domain’s DNS to decrypt the signature.
If everything matches up, the email is declared authentic and sent straight through to the inbox.
If they don’t match, well... bounce city.
Then there’s SPF (Sender Policy Framework), which takes things one step further. It confirms the server sending the email is authorized to do so by the domain. Basically, DKIM and SPF are Big Tech’s way of trying to eliminate spam—and, as it turns out, they’re also inadvertently creating business opportunities for tech experts who can implement these headaches for clients like mine.
The Ongoing Fix
The fix for this issue is straightforward-ish but definitely time-consuming. It looks like this:
Create Your DKIM Keys
We’re generating unique private-public key pairs to authenticate emails.
Update the DNS Records
Once those keys are created, they need to be added to the domain’s DNS settings.
Enable DKIM
Finally, you enable DKIM in whatever email system or provider you’re using—essentially flipping the switch so it all works together.
With SPF, similar steps involve configuring the DNS to authorize specific IPs for sending emails. Getting it all set up requires focus, attention to detail, and likely some back-and-forth testing.
Lessons Learned
To say this process felt frustrating is an understatement. But as always, challenges are the best teachers. Here are my key lessons from this saga:
Stay Ahead of Big Tech’s Rules
We live in a digital age where everything changes faster than you can send a tweet. Staying updated on email authentication methods—whether DKIM, SPF, or something else—is non-negotiable for anyone who relies on email to drive their business.
Proactive Measures Go a Long Way
A regular audit of email systems for compliance will save you from scrambles like this one. It’s not glamorous, but it’s way less stressful than dealing with bounce-back hell.
Diversify Your Communication Channels
Email is amazing—until it’s not. Having alternate ways to stay in touch with clients (like SMS, social media DMs, or carrier pigeons in a dire emergency) ensures your communication doesn’t hit a total standstill.
Prompt Action = Client Trust
When tech issues arise, time is of the essence. Acting quickly preserves client trust and keeps day-to-day operations running smoothly.
Key Takeaways
For businesses—especially those just starting out:
Audit your email systems regularly for compliance with current authentication standards like DKIM and SPF. It’s boring but necessary.
Keep learning and adapting as Big Tech introduces new standards. Whether they call it progress or gatekeeping, knowing the rules helps you stay one step ahead.
Have backup methods for communication because email alone isn’t always reliable.
Address technical issues ASAP to maintain the trust and satisfaction of your clients.
Final Thoughts
Navigating email authentication was a reminder of how even the simplest-seeming tool—email—is actually a complex beast. It’s also a testament to the importance of staying curious and proactive.
This issue isn't fully resolved yet, but we’re making progress. And as frustrating as these tech hurdles can be, they’re also opportunities to grow, learn, and—if we’re being honest—vent a little in blogs like this.
