FAQ
Which cold email platforms do you format CSV lists for?
I format lead lists for Instantly, Smartlead, Lemlist, Apollo, Mailshake, Woodpecker, and HubSpot. If you use custom software, simply provide your required column layout in the order requirements.
How do you clean company names for cold email campaigns?
I use automated workflows to remove suffixes like "Inc", "LLC", "Ltd", "Corporation", "Co", "Pty", as well as trailing punctuation, emojis, and brackets, leaving only the clean brand name (e.g., "Acme Solutions, LLC" becomes "Acme Solutions").
How do you identify and remove duplicate leads?
I deduplicate your file against unique primary identifiers (such as corporate email addresses or domain URLs) to delete repeated records without losing vital prospect information.
What is included in the Interactive Summary Dashboard extra?
The dashboard extra turns your clean dataset into a visual sheet featuring key metrics: total lead counts, top-level domain breakdowns (.com, .io, .co), geographic distribution, and interactive filter slicers for easy viewing.
Can you process large CSV files with over 25,000 rows?
Yes. I process datasets of any size. For large scraped databases (50k to 500k+ rows), send me a direct message and I will issue a tailored custom offer.
Will my lead data remain private and secure?
Yes. Your public B2B lead data is kept strictly confidential and is deleted permanently from my local drive once your order is approved.
