How We Keep Your Campaigns Landing in Inboxes
Keeping your email list clean is one of the most important things you can do to make sure your campaigns land in inboxes and not in spam. That’s why we automatically verify every new email address uploaded into the system.
This isn’t just about your clinic, it’s about protecting the sending reputation of every clinic that uses Co-Kinetic. By keeping our system “gold standard,” you benefit from the very best possible deliverability.
Why We Verify Emails
Better deliverability: Verification reduces bounces and spam complaints, so more of your messages reach inboxes.
Protects our shared sending domain: Because all emails are sent under Co-Kinetic’s domain, bad addresses from one clinic could affect everyone. Verification prevents this.
Protects your results: By maintaining the best possible sender reputation, your campaigns get stronger inbox placement and higher open rates.
What Happens if an Email Fails Verification?
That contact simply won’t be sent emails. This protects our shared sending domain and ensures your campaigns (and everyone else’s) keep landing in inboxes.
What Verification Actually Does
When you upload a list, our system automatically checks each email address using ZeroBounce, an industry-leading verification tool.
The verification process:
Removes invalid or fake addresses
Flags typos and abandoned accounts
Identifies spam traps that could damage deliverability
Allows role-based addresses (like info@ or reception@), since many clinics use these
Allows catch-all domains (these are not blocked, but flagged internally)
How the Process Works
One-time check: Every new email uploaded is verified.
6-month cycle: Each address is re-verified automatically every 6 months to make sure it’s still safe to send to.
No double-charging: If you upload a list containing emails that have already been verified, the system recognises them and skips re-verification.
Credits and Costs
Verification does use credits, but only at cost, we don’t add a markup.
One credit = £0.08 (8p)
Only new or expired addresses are charged.
On average, each credit covers around 17 email verifications, here’s what that looks like in practice:
List Size | Approx. Price | Credits Needed |
1,000 | ~£4.74 | 59 credits |
5,000 | ~£23.70 | 296 credits |
10,000 | ~£47.40 | 593 credits |
Because we automatically skip duplicates and recently verified addresses, your actual costs will almost always be lower than a raw list count.
What This Means for You
Higher inbox placement = better open rates
Fewer bounces and fewer headaches
Stronger sender reputation over time
The peace of mind that your campaigns are being delivered using industry best practice
This process is a key part of ensuring your clinic’s marketing works as hard as possible, without wasting time or money.
