There's no single best cold email software. Saleshandy has the most reliable warmup we've used and is our default for new domains, Instantly and Smartlead are built for large multi-inbox volume, and Apollo combines a contact database with sequencing for teams that want one tool. Pair any of them with a verification tool and a CRM. Below is how we choose for each client, based on running all of them.
Prices below are the monthly figures on each vendor's own pricing page, checked October 18, 2026. Annual billing is lower where that page says so. A verification tool and a data source still sit on top of these fees.
Quick verdict for four cold email platforms. Prices checked October 18, 2026.

Instantly
You need unlimited mailboxes and a fast campaign setup.
Outreach Growth is $47 a month. Hypergrowth is $97 a month. Light Speed is $358 a month.
Both pages were open on October 18, 2026. Saleshandy Starter, billed annually, is $34 a month and includes unlimited email warm-up on the connected mailboxes. Paid monthly, that same Starter plan is $41. Smartlead Base is $39 a month and the FAQ says every plan includes unlimited email accounts. Smartlead's send cap on Base is 6,000 emails a month. Saleshandy Starter lists 6,000 emails a month as well, then Pro and Scale raise the cap. Choose Saleshandy when the warmup record is the reason you are switching tools. Choose Smartlead when you want the Unlimited Smart plan at $174 a month and the API that agencies use to run many clients.
How to read this
We run client campaigns on all four of these platforms, so this is a practitioner's view rather than a feature checklist. The dollar lines above are what each pricing page showed on October 18, 2026. Expect to pay for a verification tool and a data source on top. If you would rather not run these tools yourself, our done for you cold email agency runs them for you.

Saleshandy
Our default for new sending domains. The warmup has been the most reliable of the four in our programs, the unified inbox is clean, and it's the tool we recommend to founders who want to check a campaign once a week and get on with the business. The trade-off is that at very large volumes the platforms built for scale give you more control.
Instantly
Built for volume. Unlimited inboxes, a big warmup network, quick campaign setup and a benchmark report we cite throughout these guides. It's the right choice when a program needs dozens of domains running in parallel and the team is comfortable managing them.
Smartlead
Similar scale to Instantly with more knobs: sub-sequences, detailed per-inbox settings and an API that suits agencies running many clients. More to learn, more control once you have.
Apollo
Different category. Apollo is a contact database with sequencing attached, so a small team can find prospects, verify emails and send from one screen. We use it heavily for list building, and it's a sensible single tool for a company that isn't ready to run a separate sending platform. For high-volume cold email we still pair it with one of the three above.
The tools around the platform
Data: Apollo and Clay for finding and enriching contacts.
Verification: ZeroBounce or MillionVerifier before every send. Instantly's report sets 2% as the bounce ceiling, and verification is how you stay well under it.
CRM: Salesforce for teams that already live in it. We run plain-text sends through Salesforce for some clients and keep the cold platforms for volume.
Automation: n8n to move replies, meetings and lead data between all of the above.
How we choose for a client
Under 10 inboxes, founder-run: Saleshandy.
Twenty inboxes or more, growing: Instantly or Smartlead, depending on who will manage it.
Small team that wants one login: Apollo, with a sending platform added when volume justifies it.
Already on Salesforce with a sales team: Salesforce for the team's sends, a cold platform for the outbound program, n8n between them.
Whatever the tool, the setup underneath is the same: separate domains, SPF, DKIM and DMARC, two to three weeks of warmup and 25 to 50 emails per inbox per day. The platform is the easy part.
FAQ
What is the best cold email software for beginners?
Saleshandy, in our experience. The warmup is dependable, the interface is simple, and a founder can run a campaign with an hour a week. Apollo is a good alternative if you also need a contact database.
Instantly or Smartlead?
Both handle large multi-inbox volume well. Instantly is faster to set up. Smartlead offers more per-campaign control and a stronger API for agencies. Pick based on who will run it day to day.
Do I need a separate verification tool?
Yes, even if the platform includes verification. A second check with ZeroBounce or MillionVerifier before every send keeps bounces under 2%, which protects every domain you own.
Can I run cold email from Salesforce?
Yes, for moderate volumes of plain-text email from a sales team's own addresses. For a cold program across many domains, use a dedicated platform and connect it to Salesforce.
How long should a new domain warm before cold email software sends?
On any of these four platforms, warm a new sending domain for two to three weeks before live cold email, and publish SPF, DKIM, and DMARC first. The sequence we follow is in the email warmup guide.
