Find the subject line of your outreach email
Describe in a sentence or two what your message says. The AI proposes six short subject lines, free of spam wording.
The text you enter is sent to an AI model to produce the subject lines, then forgotten: it is neither recorded nor kept. Avoid entering personal data. Limit of 5 generations per day per address.
When to use this generator
When your message is written and the subject line is still to find, or when you want several variants for an A/B test. The subject line decides in a few words whether the email will be opened.
The tool produces leads, not truth: review them, adapt them to your voice and to what the message really contains.
How to choose among the proposals
Keep the short ones (the character count is shown) that faithfully announce the content. A misleading subject line gets the message opened once, then gets the sender reported.
To test, send two variants to two halves of your list and compare replies rather than opens, which are less reliable today. You can also run the chosen subject through the spam word checker.
Frequently asked questions
Is my text kept?
No. It is passed to an AI model to produce the subject lines, then forgotten. Only anonymous usage-limit counters are kept to prevent abuse.
Why a limit of 5 generations a day?
Each generation has a real cost for Fluenzr. The per-address limit and a global daily cap prevent abuse. To write whole sequences, FluenzR's assistant Léna is included during the 14 days of Pro offered.
Are the subject lines guaranteed spam-free?
No. The instructions given to the AI avoid capitals, fake urgency and promises, but no deliverability guarantee exists: it also depends on your domain and your list.
What subject line length should I aim for?
Around 30 to 50 characters, to stay readable on mobile. Beyond 60, the end is cut off in most mail apps.
