Your cold email campaigns will fail without the right infrastructure. A solid domain provider ensures your emails aren’t blocked by spam filters.

Godaddy or Porbun provide the security and reliability you need, and their DNS management tools make it easy to set up SPF and DKIM records.

These are like verification badges for your emails, signaling to email providers that your messages are legitimate.

This reduces the chances of your emails ending up in spam folders. It is crucial when you're sending outreach at scale.

For creating an email account we have a couple of options in cold email

1.Google workspace
2.Outlook
3.Private SMTP Providers.

If you are a beginner in cold email, I wouldn't recommend using private ones. Because it is more tricky and completely built for agency owners that use this operation with very high volume. Just use Google Workspace and Outlook. They are the safest options. Don't create more than 2 accounts per domain. if you do, it could affect your deliverability harshly.

Domain addresses must not be the same domain you use actively. Because we don't want to waste your active accounts that you are communicating with your client. This is why you need to buy multiple domains in order to increase your email volume.

you can name your domain like this.

getairtable.com
tryairtable.com
airtablesolutions.com
airtabletry.com
airtableget.com

For example, you can automatically pull in a recipient’s company name or recent press coverage, adding relevance to your outreach.

These platforms also integrate with your CRM, managing lead management and making sure that follow-ups are scheduled and tracked automatically.

Without these tools, you’re flying blind—unsure of whether your emails are landing in inboxes or making an impact.

You can also use these tools easily to track domain and account health;

Our goal is to show that your outreach isn’t just one of a hundred emails they’ve received, but something specifically crafted for their needs.

If you start thinking about how you can personalize the email, you will see There are tons of ways to do that.

That being said, You should focus on these things seriously if you don't want to miss opportunities.

Cold emails can easily go wrong if you don’t know the traps to avoid. For starters, never attach files to your initial email—it’s a huge red flag for spam filters and potential recipients alike. People are hesitant to open attachments from unknown senders because they could contain malware. Instead, link to resources on your website or provide a call-to-action that leads them to your landing page. Keep your email short and concise; if your recipient has to scroll to read it, you’ve likely lost their attention.

Subject lines should be clear, not misleading. Something like “RE: Our conversation” when you’ve never spoken before just annoys the recipient and reduces your credibility.

Avoid being overly familiar too—terms like “buddy” or “rockstar” can come off as disingenuous if you haven’t established a relationship. Your goal is to be professional but approachable, balancing friendliness with respect for their time.

The list of what you shouldn't use in cold email.

Similarly, you can test different email copy, like a short version versus a longer story-based version, or experiment with different call-to-actions like “Book a Call” vs. “Let’s Chat.” Make sure to test one element at a time, so you can understand what’s making the difference.

Over time, this data helps you refine your strategy, continually improving your open, reply, and conversion rates. A/B testing isn’t just for big campaigns either; even smaller lists can benefit from consistent optimization.

You might think if someone doesn’t respond to your first email, they’re not interested. But that’s rarely the case. Most people are busy, and your email might have gotten lost in their inbox.

This is why you need to follow up your leads consistently. It shouldnt be something we underestimate.

A well-timed follow-up can often land you the response you’re looking for. The key is to space your follow-ups appropriately and add value each time. Don’t just send a “Did you see my last email?” message. Instead, include new information, like a relevant case study or an article that aligns with their business.

Each follow-up should feel fresh, not repetitive. Persistence pays off, but you have to balance it with respect for their time. A structured follow-up sequence, such as 3-4 days after the initial email, then again after 7 and 14 days, will increase your chances of getting a response without coming off as pushy.

if you send more than 3 follow-ups it could get your lead annoyed and you could see some negative returns. This damages the reputation of your company.

Similarly, your website should clearly communicate your value proposition—nothing kills credibility faster than an outdated or poorly designed site.

Testimonials and case studies are also invaluable. If you don’t have any yet, consider offering your services at a discount to a few initial clients in exchange for a testimonial
