The best cold email subject lines don’t sound like cold emails. This subject line leverages commonalities you have with a prospect. This shows them you’re a real person and have actually taken the time to learn a little bit about. Them.

With more than a decade of experience sending sales emails, we’ve learned a bit about nailing your email subject lines. Here are our top tips for email subject lines that actually start conversations with prospects:
1. Really Get to Know Your Potential Customers & Prospects
Before crafting email subject lines, take time to really get to know your target audience. Don’t just think about what you want them to do; think about what topics they care about. What pain point keeps them up at night? How does seasonality impact their industry? When you really know who you’re talking to, you can tailor your subject lines to resonate with their needs.
Consider collaboration with other teams, including your support and marketing team to understand what language is likely to resonate with your target audience. Use all this info to create hyper-personalized, relevant subject lines. You can also check out our 61 proven email subject lines for more inspiration.
2. Keep Your Email Subject Lines Short (Especially for Cold Emails!)
The subject line is, without a doubt, the most crucial part of any email campaign. Why? Because if it fails to grab your prospects' attention, they won't even bother opening your email, and all your hard work will go down the drain.
Entonces, ¿cuál es el secreto para crear un asunto de correo electrónico irresistible?
Keep it short and sweet. You could go on and on with a lengthy subject line, but guess what? Email clients will just chop it off. Do yourself a favor and stick to a neat 20 to 40 characters.
3. Atraerlos con un anzuelo intrigante
Párate un momento y echa un vistazo a tu ajetreada bandeja de entrada. Lo más probable es que encuentres un enjambre de correos electrónicos compitiendo ansiosamente por tu atención. Ahora, imagínese esto: su asunto es el señuelo brillante, el cebo irresistible que puede atraer a sus clientes potenciales a picar o hacer que se alejen nadando.
How do you ensure your hook is irresistible? It's all about standing out from the crowd. Consider leveraging the power of curiosity, posing a thought-provoking question, or teasing them with a tantalizing hint of what awaits in your email.
Remember, the goal is to build a genuine connection with your prospects from the subject line right through the closing line.
4. Evita el spam (y piensa bien en los emojis)
The best subject lines are catchy and pique your contact’s interest. But your email subject lines can also land you in the spam box. Most email providers use spam filters and algorithms that send emails with specific words straight to the spam folder. So, how do you avoid the spam box? Avoid using spam words like:
- Efectivo
- Gratis
- Cobrar ahora
- Perfecto
- Increíble
- 100% de descuento
- Cura
- Actúa ya
Emojis are another feature that can kill your email marketing campaign before it's even started. One study found emojis increase negative sentiment towards emails and don’t increase open rates. They might make sense for your audience, but take some time to consider whether it's really a good fit before testing.
5. Inyectar (un poco de) urgencia
Spare us the cliché subject lines like "LAST CHANCE BEFORE THIS AWESOME DEAL IS GONE FOREVER." That's so 2010. Instead, infuse your subject line with genuine urgency. Highlight the benefits they'll miss out on or the amazing results they could achieve with your help.
Considere la posibilidad de añadir ofertas específicas, cifras o un período de tiempo que destaque lo que realmente se están perdiendo si no abren su correo electrónico.
6. Copie bien su correo electrónico
Good email subject lines are just the start. Whether you’re sending cold emails or trying to sign ups for a webinar you’re hosting, take the time to craft email content that provides value, addresses customer pain points, or convinces them to hit that ‘reply’ button. The content of your email can make or break a campaign’s success, so don’t leave your audience hanging.
And if you’re not a copywriting expert, consider using our cold email generator to create your entire first draft. Just provide key info about your business and the type of email you want to create, then hit ‘generate.’
