## What Is A Cold Email?

A cold email is an initial email sent to a prospect without prior contact. Similar to cold calling, a cold email is less intrusive and, when properly prepared, a great way to initiate a conversation. [Instantly, the **cold email platform**](https://instantly.ai/?ref=instantly.ai) built for professional outreach, automates your email warmup process to save time and fully optimize deliverability before you launch campaigns.

But since cold emails are unsolicited emails, how do they differ from spam?

Unlike bulk spam, cold emails target a relevant audience, are more personalized, and don’t include fake or deceiving content. The primary goal of a cold email is to start a conversation and ultimately exchange value.

### What Is Cold Email Marketing?

Cold email marketing is a marketing strategy that uses cold emails as the first step of communication with a list of prospects.

## Cold Email Marketing Strategy

Without further ado, let’s go over strategies you can use to maximize the results of your cold email outreach campaign.

### Setting Up Your Cold Outreach Strategy

Before going all in, we want to make sure our emails look professional and don’t end up in the spam folder. We can do this by:
- Choosing the right email service provider.
- Having an authentic email profile.
- Adding an email signature.

**Choosing the Right Email Service Provider**

Email services can be either paid (e.g. name@companyname.com) or free, like a free Gmail account.

Going the paid route is always recommended for an email campaign.

That’s because paid domain emails:
- Look more professional.
- Have higher daily sending limits.
- Are more trusted by humans and email spam filters.

**Having an Authentic Email Profile**

Having a welcoming email profile picture will put a face to your name and make your outreach more professional by adding that extra layer of authenticity.

**Adding an Email Signature**

Like most aspects of email outreach, keeping things simple is the way to go, and that includes signatures.

But unknown to many, a signature is a great place to get more value out of your outreach.

Apart from your name, professional title, contact information, and social media links, you can also [maximize your signature](https://blog.hubspot.com/marketing/professional-email-signatures?ref=instantly.ai) by adding a call to action or booking links.

### Avoiding The Spam Folder

Now that you have a professional email account set up, the primary goal is reaching prospects without landing in the spam folder.

**1. Setting Up Email Authentication**

Email providers verify where and who emails are coming from through SPF, DKIM, and DMARC protocols.

Before we get too tangled up in the technicals, you can check your SPF and DKIM status with these tools:

- [Google Apps Toolbox](https://toolbox.googleapps.com/apps/checkmx/?ref=instantly.ai)

**2. Setting Up a Custom Tracking Domain**

Having a custom tracking domain allows you to track open rates for your emails using your own exclusive tracker.

**3. Email Account Warm Up**

A brand new email account will have sending limitations and will need [warming up](https://help.instantly.ai/en/articles/5975329-how-warm-up-works-and-why-it-s-important?ref=instantly.ai) to prove it’s being used by a real person before it can send cold emails in bulk quantities.

**4. Verifying Emails Before Sending**

Before starting a large-scale cold email outreach campaign, it’s important to know if the email addresses in your list are valid.

### Collecting An Email List

You don’t want to send a cold email to just anyone, but rather to a relevant target audience.

When it comes to building an email list, it can be done through opt-in lead generation or by going out and manually looking for emails. Be sure to:
- Save your email list as a CSV file.
- Use trusted sources to collect emails (LinkedIn, Facebook, business websites, etc.)

### Writing Cold Emails That Get Replies

Writing a targeted cold email using tried and tested methods will make your email stand out and shine. And it starts with…

**1. The Subject Line**
   - Personalization.
   - Being straightforward.
   - Building intrigue.

**2. The Introduction**
   - Mentioning shared interests, targeting a pain point, or giving a genuine compliment.

**3. Compelling Email Body**
   - Clear and straightforward communication.

**4. Call-To-Action**
   - A necessary invitation for the recipient to take action.

### Sending Cold Emails In Bulk

Daily limits depend on the email provider. Examples include:
- Free Gmail account: up to 500 messages per day.
- Google Workspace: 2000 messages per day.
- Office365: 1000 messages per day for non-relationship recipients.

A successful cold email campaign can yield some of the best ROI for your business. Using these strategies and keeping track of metrics will help you understand what’s working and what needs tweaking to get the most out of your cold outreach campaign.
