If offersList array is empty, it's length will equal to 0. You can make easy condition:

<div className="container">
  <h1>Main {offersList.length}</h1>
  { offersList.length ? offersList : <p>No Result</p> }
</div>

With a ternary operator:

<main>
   <div className="container">
     <h1>Main {offersList.length}</h1>
     { offersList.length ? offersList : <p>No result</p> }
   </div>
 </main>
