Remarketing vs. Retargeting: Different Tools or Different Names?
One proposal offers remarketing and another offers retargeting. The names alone will not tell you whether either plan uses ads, email, customer lists, or some combination.

The short answer
Remarketing and retargeting are overlapping terms for reaching people who have previously interacted with a business. Some marketers distinguish them by channel or audience source, but there is no universal rule that one always means email and the other always means advertising. The useful definition is the actual audience, channel, data source, permission basis, and intended next step.
What this means in everyday life
A campaign might show ads to eligible past website visitors, contact opted-in customers by email, or use an approved customer audience within an advertising platform. These workflows have different technical requirements and privacy implications. Someone who visited a page is not necessarily identifiable, eligible for an audience, or interested in further messages. Browser restrictions, consent, account settings, and platform policies can limit what is possible.
Where the misunderstanding causes trouble
Do not assume prior contact is blanket permission for every new use of customer information. Applicable laws, notices, consent requirements, and platform rules need review. Sensitive topics can carry additional restrictions. A supplier should explain how audience data is collected and used without promising that every visitor can be followed around the internet. Be especially cautious when a proposal treats customer-list uploads as an automatic administrative step.
A practical business example
Imagine a hypothetical outdoor-equipment retailer planning to reconnect with previous shoppers. One supplier proposes ads for consenting website visitors who viewed camping gear. Another proposes an email to existing subscribers about a seasonal checklist. Both call their work remarketing. The retailer compares the audience, permissions, content, budget, and goal rather than treating the identical label as evidence that the services are interchangeable.
What to ask before deciding
Set limits around timing, repetition, exclusions, and measurement. Someone who has already bought may need to leave a particular acquisition audience, while an existing customer could still benefit from an appropriate follow-up. Make those choices intentionally. Assess incremental value carefully, since returning customers might have purchased without the campaign. The goal is a relevant reminder that respects the relationship, not maximum repetition aimed at everyone who ever interacted with the business.
One useful next step
Ask the provider to describe one proposed campaign without either label. Who would receive it, through which channel, based on what interaction, for how long, and with what exclusions? Confirm the required permissions before sharing data or enabling tracking. Review the actual message and destination. A plain description makes it easier to spot both useful opportunities and assumptions that need correction.
The takeaway
Define the workflow before debating the word. Audience, channel, permission, and purpose will tell you far more about a re-engagement campaign than whether its title says remarketing or retargeting.
Cookies can support some audience-recognition methods, while Customer relationship management may supply a different source of relationship data with its own permission requirements.
Questions you might still have
Is retargeting always advertising and remarketing always email?
No. Some marketers use that distinction, but usage varies. Ask each provider to define the terms in its proposal and specify the actual channels and audience sources.
Can every website visitor be retargeted?
No. Consent, browser behavior, platform eligibility, audience thresholds, and other limits affect what is possible. Do not treat a website visit as guaranteed identification or permission.
How should we judge whether the campaign helps?
Use a clear outcome, suitable comparison methods where feasible, and awareness of existing customer intent. Recorded conversions alone do not prove the campaign caused every purchase.
