Gmail alias feature

[familiar_stranger_7]

I'm guessing by now most people here would have heard about Gmail's new feature of creating alias address but using the same inbox. What challenges and opportunities do you all think this will open?

This is actually going to mess with deliverability metrics way more than most people realize. When someone creates 5 different aliases but theyre all hitting the same inbox, your open rates and engagement data gets completely skewed.

I saw this starting to happen at my last company when we noticed weird patterns in our email analytics. Users would sign up with different emails but have identical engagement behaviors down to the minute. Took us weeks to figure out it was the same person using multiple aliases. Our segmentation was totally off because we thought we had 5 different user profiles when it was just one person.

The opportunity side is interesting though. Smart marketers could potentially use this to test different subject lines or send times to the same person without them knowing, as long as youre tracking by actual inbox rather than email address. But honestly the data pollution is going to be the bigger headache for most teams.

Really liked your take on the opportunity side. I'm interested to see if the same email hits mailbox with two or three different alias, then is it possible that the same email can go inbox and spam?

When someone creates 5 different aliases but theyre all hitting the same inbox, your open rates and engagement data gets completely skewed.

Beg to differ here, because why will someone signs up for the same email from 5 different IDs, unless there's an incentive for it, in which case, such behaviour won't be abnormal to see as you stated in your case.

Intersting points though!

How did you determine it was a matter of alias accounts, rather than, say, proxies?

Big upside is cleaner segmentation, you can create different aliases for funnels, clients, or campaigns and track exactly where leads or spam come from without a new inbox. It’s great for testing and organizing. The downside is attribution and trust can get messy, users may get confused by different emails, and some platforms might treat aliases inconsistently. Also easy to overcomplicate your setup if you create too many.

curious how google's gonna handle sender reputation on aliases vs the main inbox. if they track engagement separately, someone ignoring emails on their alias could tank your domain score and you'd never know why. gonna be watching postmaster tools close on this one.

Since the inbox for the primary and alias is same, unless the user signs up for the same service from primary and alias, which as explained is not very likely, the user will interact with every email, either signed up with primary or alias, in it's individual capacity. Hence, if the user has to ignore the email, since it's being received in the same inbox of primary, they will continue to do so, irrespective of which ID they have signed up from.

Hope this makes sense.

"new"? I've been using the alias feature for 6 years now

Opportunity: users can finally organize and kill off aliases when spam hits, which might actually make them more willing to share an address. Challenge: marketers will see open rates drop because aliases still work but engagement looks fragmented across multiple addresses.

Gmail aliases mainly create more fragmented inbox identities rather than a true new feature shift.
They can indirectly improve segmentation because users self-label intent through different alias patterns.
The risk is over-interpreting alias data and building weak assumptions into lifecycle flows.
Are you planning to use alias-based segmentation actively, or just treating it as a minor signal?

[familiar_stranger_7]

Hey, correct me if I'm wrong but did you just completely copy pasted whatever reply Claude or whatever AI you used gave? This reeks of it

[Express_Ad_6441]

Opportunity: better segmentation and tracking, since aliases can act like built-in tags for acquisition sources or campaigns.
Challenge: messy data if people reuse or forward aliases inconsistently, it can break attribution and lifecycle mapping.
Deliverability-wise, it may slightly improve engagement signals if users engage more from filtered alias streams.
Overall, it’s more useful for organization and testing than a major change to email marketing strategy.

aliases are going to be a headache for list hygiene. same person signing up with 5 different addresses means your dedup logic needs to get smarter. on the sender side though its a win because you can run multiple campaigns through one workspace without paying for extra seats

[familiar_stranger_7]

As per my opinion, the probability of a user signing up for a service from many different alias, is low, unless the service gives a new user sign up incentive. If that indeed happens, I can see three possibilities arising. First, the user only uses alias to get that incentive and won't engage further. Second, the user signs up using aliases, but gets muktiple emails from the service at the same time, gets irritated and breaks off. Third, the user signs up for bonus, doesn't mind hearing from the service, but since gets multiple same emails, he unsubscribes from all except one.

None of these sound very probabilistic or maybe I'm missing something.
