Whether you get turned down for a promotion or you get denied for a raise, rejection stings. And for most people, rejection seems final.

But, real estate mogul Barbara Corcoran isn't most people. She's used to fighting for what she wants even after being told no.

In 2008, she landed a part of the ABC series "Shark Tank." Shortly after signing the contract, she got a call from the show saying they'd changed their minds. They'd cast another woman in the role.

But rather than accept ABC's decision, Corcoran fought back. She wrote an email so powerful that the producer, Mark Burnett, gave her another chance (see this Business Insider article for the full email).

Of course, we all know what happened next--Corcoran proved she was the best shark for the job and she's gone on to become a fan favorite.

Why Corcoran's Email Got Producers to Rethink Their Rejection

It's hard to convince someone who rejected you to give you a second chance. After all, their minds are made up and they've decided you're not a good fit.

But Corcoran's letter proves you don't have to take no for answer. She created a blueprint for responding to rejection that clearly worked for her.

Here are three reasons why Corcoran's email was successful in getting the producers to give her another chance:

1. She asked for a chance to prove herself.

Corcoran didn't demand she be given the job. Instead, she asked for a chance to prove she was the best person for the job.

Rather than say, "I'm better than the other woman," she said, "I think you should consider inviting us both to LA for your tryouts."

She showed that she believed in herself and she had faith that if given the chance, she could prove that she would be a good shark.

2. She didn't whine, complain, or lash out.

When you're rejected, it's tempting to say, "This isn't fair," or "You're making a big mistake and you're going to be sorry." But Corcoran didn't waste any time whining, complaining, or lashing out even though they'd essentially taken the job away from her after they'd given it to her.

Instead, Corcoran painted herself as the ultimate comeback kid. But rather than simply insist she does well when backed into a corner, she offered specific examples of times she's beat the odds and exceeded everyone's expectations.

She made it clear that she trusted Burnett's decision-making skills and she said she knew he'd make a good choice. If she'd insulted him the outcome might have been very different.

3. She outlined the reasons why she was the best person for the job.

Corcoran could have made the letter about her--by saying she needed the job or that she'd already told everyone she landed the role. But doing so would have made her look desperate.

Instead of insisting they owed her the role, she focused on what she could do for them. "My style is different than the other sharks' and your audience would fall in love with me."

She was confident that if given the chance, she could add value to the show. And clearly, that compelled Burnett to give her a shot.

No May Not Be the Final Answer

The next time you're rejected for a job, a raise, or a promotion, consider using Corcoran's blueprint to draft your own letter. You might find that you're able to convince someone to give you a second chance.
