Will Flodesk Send Duplicate Emails to My Subscribers?
Overview
No, Flodesk will not send the same email twice to a subscriber, even if they’re in multiple segments.
Each subscriber record in Flodesk is unique, and the platform automatically ensures that subscribers only receive one copy of your email, even when they belong to several segments at once.
How it works
In Flodesk, segments act as labels that describe a subscriber’s interests or behaviors, not separate instances of that subscriber.
That means if a subscriber is in multiple segments (for example: Newsletter, Customers, and VIP List), they’re still only counted once in your total audience. And more importantly, they’ll only receive one copy of your email if you send it to all three segments at once.
Example
Let’s say you’re sending an email to:
Segment A
Segment B
And your subscriber, Rebecca is in both of those segments.
When you hit send, Flodesk automatically ensures Rebecca only receives one copy, not two.
You don’t have to do anything extra. Flodesk handles the logic for you behind the scenes.
Troubleshooting: A subscriber still receives multiple copies
In rare cases, a subscriber might see multiple copies of the same email in their inbox.
Here’s what to check:
Confirm there are no duplicate records
Search the subscriber’s email address in your Audience. Flodesk sends one email per subscriber record.Rule out inbox-side forwarding or filtering
Sometimes a subscriber’s own inbox settings (like forwarding rules) can cause duplicates.Check for Apple “Hide My Email” addresses
Some Apple users have multiple private relay addresses that forward to their main inbox.
Each Hide My Email address appears as a separate subscriber in Flodesk, even if they all belong to the same person.If the subscriber uses several active Hide My Email addresses, each one will receive its own copy of your campaign.
To fix this, unsubscribe or remove the extra Hide My Email addresses. Once only one address remains active, duplicates stop.
What this means for you
No duplicates — Each unique subscriber record gets one email.
Accurate counts — Flodesk counts each subscriber once toward your audience total.
Transparency — If duplicates occur, they’re almost always linked to inbox behavior (like Apple’s Hide My Email), not to Flodesk sending logic.
Summary
If a subscriber is in more than one segment and you send an email to multiple segments at once, they’ll only receive it once.
If a subscriber reports receiving multiple copies, check for:
Duplicate subscriber records,
Forwarding rules, or
Multiple “Hide My Email” addresses.
Once any extra addresses are unsubscribed, the issue is resolved.
FAQ: Duplicate emails in Flodesk
Q: Will Flodesk send duplicate emails to my subscribers?
No. Flodesk automatically ensures each subscriber receives only one copy of your email, even if they’re in multiple segments, if you email those segments at once.
Q: My subscriber received the same email more than once. Why?
This can happen when the subscriber has multiple Apple “Hide My Email” addresses forwarding to the same inbox. Each Hide My Email address acts as a unique subscriber record in Flodesk, so each receives its own copy.
Also, if you send the same email separately to multiple segments, subscribers may receive multiple copies.
Q: How can I fix duplicate email deliveries?
Search your Audience for duplicate records.
Confirm the subscriber isn’t using inbox forwarding or filtering rules.
If they use Apple “Hide My Email,” unsubscribe or delete the extra relay addresses.
Once only one address remains active, the duplicate emails stop.
