Frequently Asked Questions
What is the most affordable cold email tool for a small sales team? +
Lemlist and Smartlead both start at $39/mo per seat. For a solo rep, either is affordable. For teams of 3+, Instantly's flat-fee model becomes cheaper — you pay one fixed rate regardless of how many people use it.
Which cold email platform has the best deliverability? +
Instantly is widely regarded as the deliverability leader — its unlimited sending account model lets you spread volume across many inboxes, reducing spam risk. All three tools include warmup, but Instantly's architecture is optimized around high-volume sending.
Can I use cold email tools with Gmail and Outlook? +
Yes. All three tools — Instantly, Lemlist, and Smartlead — connect to Gmail, Google Workspace, and Outlook/Microsoft 365 via OAuth. They send from your actual email accounts rather than shared sending infrastructure.
