5. Do your LinkedIn search

Define your target

Before sending out your first prospecting emails, remember to define your target precisely.

Most important thing to keep in mind: be precise! The quality of your leads should be more important to you than the quantity.

Perform a LinkedIn search

Once your target has been defined, do a search on LinkedIn and be as precise as possible.

  • Sector of activity
  • Country
  • Position held
  • Exclusion criteria: it is imperative to refine your search, and exclude, for example, trainees, investors....
  • Spoken Language

To become a pro at LinkedIn search, you must use the advanced search, boolean, and especially negative filters :

  • AND: selection of several words: useful in combined searches
  • OR: choice of either term
  • NOT: exclusion of a word from the search.
  • Quotation marks: expression of related keywords
  • Brackets: sa uccession of conditions

Note that the system first deals with what is in brackets. We advise using Sales Navigator so that you are not limited in your searches.

๐ŸŽˆ Let's make a concrete use case: You are looking to get in touch with the marketing department, here is what your LinkedIn search could look like:

title: marketing AND (responsible OR CMO OR "Head of" OR Director) NOT (Trainee OR Internship OR Alternating OR Internship OR Alternating OR Investor OR Assistant OR Assistant)

Check whether your results are in relation to your target.

6. Install the Phantombuster cookie

10. Test, iterate, improve

All you will have to do is analyze the results and optimize the subject, the content and the CTA as you go along.

You could easily reach:

  • An opening rate > 60% on the sending of at least 3 or 4 mails
  • A response rate > 25%.
Test, test and, test again. Start with "small sends" of 25 to 50 emails a day and iterate until you get results that reach new heights ๐Ÿ”

What about GDPR?

This commercial approach ๐Ÿ‘†๐Ÿป is a B2B practice and can in no way be used to prospect personal email addresses.

When it comes to BtoB, GDPR allows the commercial approach if (and only if) the prospect has the possibility to oppose this practice and to stop the approach at any time.

Some tips

๐Ÿ’ก Depending on your strategy, you can, in the same workflow, send a connection invitation to all the targeted profiles of your search (select "invite the lead to join your connections")

๐Ÿ’ก LinkedIn limits the number of profile searches, so don't be greedy, and remember to limit the number of queries per phantom trigger.
