Replaced Apollo overnight. Reply rate went from 2% to 14% in week one. Wish I found this sooner.
Natasha B.Founder, B2B SaaS · Verified on Trustpilot★★★★★
I sent 300 emails on day one. By week 2 I had a closed deal. The verification alone is worth it.
Carlos V.Sales Lead, Series B · Verified on Trustpilot★★★★★
47 demos booked in 30 days. The unlimited sending is a game changer, I used to pay $300/mo for half this.

Profiles
Each tool, in short
Instantly
4.6/5 · $47-358/mo
Instantly made unlimited-inbox cold email a category and has strong agency workspaces. But its lead database and verification are separate paid products, so a full setup stacks into three subscriptions.
Pros
Unlimited sending accounts
Mature agency multi-workspace tooling
Built-in warm-up
Cons
Leads and verification cost extra
Feature gating on tiers
Deliverability complaints at scale
Smartlead
4.6/5 · $39-94/mo
Smartlead is the sender's sender: unlimited mailbox rotation, a mature API and white-label options. But it brings no lead data and no verification, so a real setup means Smartlead plus a database plus a verifier.
Pros
Unlimited mailboxes on all plans
Powerful API and white label
Strong warm-up and rotation
Cons
No native lead database
No built-in verification
Steeper learning curve

The third option
The third option: skip the subscription stack
Both tools above bill monthly, and neither covers the full workflow alone. Getlead bundles the lead database, SMTP verification, cold email sending and warm-up in one flat plan from $19.90 a month.

Price
Getlead
Founders, freelancers and agencies who want the entire lead gen and cold email stack for one flat monthly plan.
For non-technical teams, Instantly's polish wins. For technical agencies that need API depth and white label, Smartlead wins. Deliverability fundamentals are comparable when configured properly.
Is Smartlead cheaper than Instantly?
Generally yes at equivalent capability: Smartlead's $94 Pro tier covers what often requires Instantly's higher tiers plus add-ons.
Do either include lead data?
Smartlead includes none. Instantly sells leads as a separate subscription. Either way, data is an extra line item.
What if I need data and sending together?
Getlead combines both: a 177M+ database, verification and 300K sends a month with warm-up for a flat $19.90 a month instead of a sender subscription plus a data subscription.
