Contacto por correo electrónico en frío para nuevas empresas

Un blog invitado de Rimma Sytnik (Senior Digital Marketer de Reply)

Running a startup is hard work. And out of all the items on a startup owner’s to-do list, outreach should be hovering around the top of the list. Whether it’s prospective customers, investors, partners, or candidates you’re trying to connect with, there’s no better way to do that than a cold email.

Now, cold email doesn’t exactly have the best of reputations. Besides the usual claims that email is dead and you simply must be on the latest social media craze, the ‘cold’ aspect leaves plenty of people… well, cold 🥶

Well, not only is email alive and well, but cold email (when done correctly) could be a solid foundation for growing your startup. It’s how we grew Reply, and while we’ve branched out into other channels over time, our outbound cold email is still at the core of our business, and it can be at the core of yours too.

So, in this article, I’d love to share some of the pro tips and best practices on how to do that.

¿Qué es exactamente el correo electrónico en frío?

Cold email is simply emailing people who you’ve not had contact with previously, whether when looking for investments, offering a partnership, growing your team, or trying to get your first customers.

Así que.., how’s that different from spam?

First off, this is where I get to tell you I’m not a lawyer (even though I’ve read a lot of John Grisham novels), and what I say is in no way legal advice. Regulations change, and you should do your own research to make sure your emails are in line with the requirements of your country (and the country you’re sending emails to if they’re different).

A good starting point is to familiarize yourself with the US Can-Spam regulations or the corresponding EU policies. Little details such as making sure you have your contact details visible and including an option for people to unsubscribe from future emails will help keep your cold email compliant.

¿Es el correo electrónico frío para todos?

While I honestly think every business can benefit from cold emailing, there are definitely some businesses that’ll benefit more from it than others.

Sin embargo, lo que hay que tener en cuenta no es si una campaña de correo electrónico en frío es adecuada para usted, sino si sería adecuada para sus clientes potenciales.

The number one question: do they have an email address? While that seems like a silly question, I personally know old-school CEOs who barely look at their inbox 📠 For some B2C businesses, your target market may despise computers.

Yet, if your prospects are online, then they’re likely using email.

¿Por qué no utilizar las redes sociales?

Now, I can hear someone saying that while their prospects may be online, they spend all their time on social – looking at cat videos on Facebook and lip-synching on TikTok maybe networking on Linkedin.

That’s a fair point. They’re all great platforms, and we regularly post content (along with paid ads) on Facebook, LinkedIn, Quora, and more.

But while we use these social platforms, they’ll never come close to email. Why?

  • Hoy aquí, mañana ya no. While some social networks last longer than others, it’s only a matter of time before the next hot trend comes along. You can either try jumping on every platform, which is a huge effort, or risk picking the wrong one and losing out.
  • Su plataforma, sus reglas. This goes out to everyone who was building an organic presence on Facebook. When they throttled the organic traffic, essentially making it a pay-to-play platform, plenty of businesses saw their reach drop to zero overnight. Even if you’re paying, you still have to seguir sus normasque a menudo están abiertos a la interpretación y pueden cambiar en cualquier momento.
  • Su alcance es limitado. While it feels like everyone’s on Facebook, Instagram, or the like, the fact is they’re not. You can throw all the money you want at TikTok, I’m never going to see your content there (and neither are most B2B leads).

On the other hand, email is an intrinsic part of people’s lives. Most of us rely on our inbox, checking it countless times throughout our day. Many use it to plan their work, to hold important information, and keep in touch with their team and their customers.

If you want to go where the people are, that means being in their inbox 📥

¿A quién enviar correos electrónicos en frío?

El correo electrónico en frío es tan poderoso y emocionante que muchos vendedores demasiado entusiastas envían correos electrónicos promocionales a absolutamente todos los que tienen una dirección de correo electrónico.

Yeah… that’s spam 🚫, and part of the reason cold email has such a bad rep.

Su trabajo consiste en enviar un mensaje personalizado y relevante a la persona adecuada. Para lograrlo, debe enviar sus correos electrónicos a una lista altamente segmentada.

For example, let’s assume you’re selling a point of sale (POS) software. Obviously, it makes sense that you’d only want to email people who actually have retail businesses. Going a step further, you might only want to target those who are located in a certain region or country or have a certain size store.

So what about your product/service? Who’s your target market? Hopefully, that’s something that was considered in the first stages of your startup. It’s a lot easier to come up with an Ideal Customer Profile (ICP) early on.

On the other hand, it might be tempting to say that your product is for everyone and that every single person on the planet needs and wants what you’re offering.

Alerta Spoiler: It isn’t, and they don’t.

Even if you’re selling water, there’s a massive difference between selling to the no-frills market and the elite water connoisseurs, who only want water that’s been infused with unicorn tears.

The good news is that once you get specific on who you’re sending your email to, it gets a million times easier to write that email.

If you’re emailing everyone, your message will inevitably become vague and weak. However, if you’re emailing Sales Managers who work at companies with >100 employees and a turnover of $1,000,000 who are currently using Acme Products for their CRM, it suddenly becomes a lot easier to be relevant.

By being personalized and relevant, you’ll already be a million miles ahead of most of the emails clogging up junk folders. 10 relevant, personalized emails sent to the right prospects will beat 100,000 vague emails sent to random people.

Enviar un correo electrónico en frío eficaz

Ahora la gran pregunta del billón de dólares: ¿Cómo escribir un correo electrónico en frío que obtenga resultados?

Do your research 🔎

For the best cold emails, most of the work is done before you write a single word. You need to research, research, and then, do a little more research. Obviously, you must know what you’re selling inside and out, but you also have to know who you’re selling to – i.e. your target market.

And I’m not talking about a spreadsheet stuffed with demographic data. This is about knowing their beliefs, their goals, their pain points, their objections – all the things that keep your prospects awake at night.

To find that out, it’s best to actually go and talk to your existing customers. Get out from behind your computer and speak with them face-to-face. If you don’t have any customers yet, find people who you’d like to be your customer.

Get to know your ideal customer, and you’ll know what to say to your prospective customers.

Find contact details 🎯

Encontrar direcciones de correo electrónico para esas personas puede ser un poco más difícil que identificar su PCI.

While you can buy a list of names and addresses, it’s definitely a case of buyer beware. Of course, there are some reputable data providers out there. But, in most cases, you’ll be paying for unverified, incomplete, or out-of-date information. For one of the lists we tested, over 50% of the addresses were incorrect.

Por esa razón, siempre recomiendo DIY. Construir tu lista tú mismo significa que sabes que cada nombre de esa lista es uno de tus clientes ideales. También puedes aprovechar esta oportunidad para aprender un poco más sobre tus clientes.

Where can you start? I’d go with LinkedIn first. You can narrow down your search to accounts that match your exact parameters in Sales Navigator and then find those people’s email addresses one by one or in bulk (depending on the tools you use).

Write an email that’s focused on them 💌

It’s easy to get carried away when emailing your prospects. You’re proud of your company and product so it’s only natural you want to tell people all about it. Just not in your outreach emails, ok?

The prime focus of your email should be your prospect. Talk about them and the challenges they’re facing. When you do talk about your solution, it should be clearly related to how it helps them meet their objectives.

My quick trick is to imagine your prospect is in front of you, reading your email. For each line, they’re asking, “So what? What’s in it for me?”

  • The fact you’re a new company… So what?
  • The fact you’ve won an award… So what?
  • The fact your product uses 8g nanotech… So what?

To make your emails even more relevant, segment your list as much as is practical. Keeping your prospect and what’s important to them in the forefront of your mind will put you ahead of 99% of the cold emails out there.

Have a CTA 📢

Think about what you want your prospect to do after reading your email. In the perfect world, they’d become a customer or investor in the first email but, unfortunately, real life doesn’t work that way.

Así que mantén unas expectativas realistas:

  • Pedir a alguien que invierta en tu empresa tras un solo correo electrónico: Poco probable.
  • Hacer una pregunta a alguien e iniciar una conversación bidireccional: Mucho más probable.

Es decir, utilice su primer correo electrónico para intentar iniciar una conversación con su cliente potencial, en lugar de intentar cerrar la venta.

Write an effective subject line 🧲

Las líneas de asunto tienen que hacer mucho trabajo en muy poco espacio. Que su cliente potencial abra y vea su obra maestra del correo electrónico en frío depende en gran medida de la calidad de su asunto.

Cold email mistake #1 is trying to be too clever, and nowhere is this more obvious than in the subject line. Too many experts have told us we need to invoke curiosity with our subject lines, but if you’re not too careful your subject line will sound like all the others in the spam folder.

So, if you’re selling standing desks…

  • Bien: Ahorre 20% en su primer escritorio de pie
  • Mal: RE: You won’t believe what Oprah Winfrey just did on live TV

In today’s world, clarity will make you stand out far more than any click-bait headline and get you far more opens too.

Also, remember that your subject line will get cut off if it’s too long (especially on mobile devices), so definitely keep it as short as you can. At Reply, we’ve found 3-7 words to be optimal.


Ahí lo tiene. Lejos de estar muertos, los correos electrónicos fríos son una herramienta poderosa.

Even better, they don’t have to be spammy to be effective. In fact, sending personalized and relevant emails will get you the best results.

By taking the time to research your prospects and writing an email focused on them and their needs, you can use cold emails to reach your goals, whether that’s finding your first investor or winning your next customer.
