If you've ever had a member tell you "I never unsubscribed" while your account clearly shows them as unsubscribed, this one's for you. These five statuses get used interchangeably in conversation, and they mean very different things.
Let's start with the question behind the question, because it's the one that worries people most.
Does Constant Contact automatically unsubscribe someone for not opening emails?
No. We don't remove or suppress a contact because they've ignored a run of emails. The only automatic suppression we apply is based on non-existent bounces, which is a different mechanism entirely covered below. [KB 5636]
So if an active contact stops receiving your emails and they didn't unsubscribe themselves, something else is going on. Here's the full vocabulary.
Unsubscribed
Both a legal and a compliance status. Once a contact is unsubscribed, they cannot be emailed through our system, this isn't a setting you can override, and that's deliberate. [KB 5636]
The part that surprises people is how many routes lead here that the contact doesn't remember taking:
They forwarded your email to someone else, and that person clicked unsubscribe and confirmed it
They tapped the unsubscribe link without meaning to, which happens more than you'd think on a phone
Your contacts sync from an external system, and that system has them marked unsubscribed
Someone else on your account unsubscribed them manually
They came in on an upload that included them as an unsubscribe
Bounced
The email couldn't be delivered. Where the receiving server tells us why, we pass that reason through — non-existent, blocked, and so on. Bounces are per-send events, not a permanent state. [KB 6185]
Suspended
This is the one worth understanding properly, because it looks like a bug and isn't.
An address becomes suspended after it has bounced as non-existent across multiple sends and critically, that history can include sends from other Constant Contact customers, not only you. Once suspended, our system stops attempting delivery, which protects sending reputation for everyone on the platform. [KB 6185]
This produces the exact contradiction that brings people to the community: the mailbox works fine for direct one-to-one email, but every campaign bounces. The address may well be live today. The suspension is a sticky historical flag, and you can't clear it from inside your account that takes our Deliverability team.
Did Not Open
Exactly what it says, and less informative than it looks. Open tracking works through a tracking pixel, so "did not open" really means the pixel never loaded. That could be because they didn't open it or because images were blocked, or the mail never arrived. Treat low open rates as a soft signal, not a headcount.
Can I find out when and how someone unsubscribed?
Partly. An unsubscribed contact's detail page shows the unsubscribe date, which lets you work back to the campaign involved. [KB 5636] If you offer a reason field on your unsubscribe page, reasons appear in that campaign's reporting. But if they unsubscribed by another route, or skipped the reason, there's no data to show you. Full attribution isn't always available.
Does sending more often hurt delivery?
It can. Inbox providers look at patterns, and a jump from one email a month to several in a week can read as suspicious particularly if it coincides with a rise in people ignoring, deleting, or reporting your messages.
That's general deliverability behaviour rather than a Constant Contact rule, and it's worth being pragmatic about. If you run a membership organisation and you genuinely need to send a weekly bulletin, a newsletter and the occasional correction, that's a legitimate cadence. Ramp into it rather than spiking, and keep an eye on unsubscribe and complaint rates as your early warning. [KB tips on deliverability]
Should I put content in the email instead of linking to a PDF?
Mostly yes, and this is judgement rather than a documented rule. A PDF adds a step, and each step loses people especially on phones, and especially with an audience that spans a wide range of comfort with technology. Key dates, times and the headline message belong in the email body where nobody has to download anything. Keep the PDF as the full-detail version for those who want it.
If members report they can't open an attachment, that's generally on the receiving side their device, mail app or security software. It's not something your account settings control.
Where to start if this is happening to you
Pull up one affected contact and look at their detail page. Their status tells you which of the paths above you're on, and that determines whether this is a list hygiene issue, a single suspended address needing Deliverability, or a deliverability pattern worth a longer look.
If you get stuck on a specific contact, post the details here and we'll work through it.
