For the first 30 days after setting up a new email account, no emails will be sent to your leads. During this time, the email goes through a warming-up process, where emails are sent only within our network. If any emails are automatically filtered by the provider, we mark them as “not spam” to train the algorithm and ensure better deliverability for future outreach.

At Coldinbox.co, we prioritize high deliverability for your cold email campaigns. To achieve this, we avoid sending emails from a single domain or email address. Instead:

•For every ~1,000 emails sent monthly, we create a unique email address.

•For every 3–4 email addresses, we use a separate, branded domain tailored to represent your business.

This approach ensures better email deliverability, protects your primary domain, and helps maintain a professional brand image.

To ensure excellent deliverability and improve the chances of your emails being read and replied to, personalization is key. That’s why the scripts you provide—or the ones we create for you—support custom variables like the recipient’s name, position, company name, country, and more.

Here’s an example of a personalized email script with custom variables:

Subject: [First Name] – Quick Question

Body:

Hi [First Name],

I love the work you’re doing at [Company Name]!

—— Skipped ——

The variables in brackets will be automatically replaced with data from the lead list you provide (or that we source for you), ensuring each email feels tailored to the recipient.

Personalized content significantly boosts reply rates, and we strongly recommend using this approach in your scripts to maximize responses.

An email sequence is a series of emails designed to engage your ideal prospects, sent with a strategic time delay between each message. Typically, it starts with an initial email containing your sales pitch or key message, followed by several follow-up emails sent on subsequent days to maximize the chances of receiving a response.

The typical range of reply rate is between 2%~6%, however, this will vary based on:

• The industry and niche you are targeting
• Your subject line and the body content
• Your offer and pitch
