LeadAtomic vs Instantly.ai
At a glance
LeadAtomic
LeadAtomic finds and researches the companies worth writing to, drafts first emails from that research and sends them from your own mailbox. Sending runs inside limits nobody can lift. A new mailbox warms up on a ramp, each mailbox has a ceiling of 50 emails a day, and bounce brakes act on their own. All of it is on every plan.
Instantly.ai
Instantly.ai is a cold-email platform built for sending across many inboxes. Its outreach plans include unlimited email accounts, warm-up and rotation. It also sells prospect data from its own B2B database, which it puts at 450M+ contacts, and offers AI agents, a CRM, and domains and pre-warmed accounts to buy.

Dimension by dimension
| Dimension | LeadAtomic | Instantly.ai |
|---|---|---|
| Who sets the sending limits | You can set your own daily cap, up to a ceiling of 50 emails per mailbox. A new mailbox starts at 5 a day and ramps up. You cannot lift the ceiling or skip the ramp. Replies inside a conversation do not count against the cap. | You do. You set each account's daily limit and its warm-up ramp. Instantly's help centre recommends 30 campaign emails per account per day. |
| When bounces climb | Brakes watch each mailbox's bounce rate across everything it sends. At 3% you get a warning, and the mailbox sends only to addresses confirmed valid. At 4% its daily volume also drops, then climbs back a little each day. At 7% it stops. | By default a campaign pauses when its bounces pass 5%, once it has sent at least 200 emails. You can change the threshold or turn it off. BounceShield skips known high-risk recipients. |
| Address verification | A paid verification service checks every address when the account is researched. Valid addresses send, invalid ones never do, and risky or unknown ones send only while the mailbox's bounce rate is healthy. | You can verify a list when you import it, or afterwards, paid in Instantly Credits. Contacts from its own database arrive verified. |
| Where the prospects come from | Live discovery in your market: web search, business directories and map listings. Rules and an AI review score each company against your ideal customer, and you release the ones worth researching. | Its own database, SuperSearch, paid for in credits, or a list you import. |
| Sending domain | Yours: Google, Microsoft or your own SMTP. We do not sell, share or pool sending domains. | Your own accounts, or domains and pre-warmed accounts bought through Instantly. |
| What the email says | Each first email is drafted from that company's research. Approval is on by default, and a message without a sender identity and a working unsubscribe link does not send. | You write the sequence. Instantly's AI Copilot can write copy and build campaigns, and its AI Reply Agent answers replies. |
| Pricing | Flat monthly plans (Starter $29 · Founders $149 · Growth $299). Each sets how many accounts get researched a month. One sign-in per workspace. | Separate plans for outreach and for database credits, plus bundles of both. The cheapest of each is $47 a month: Growth for outreach, and Growth Credits for 1,500 to 2,000 database credits a month. |
| Your data | Your research is your own copy, stored in your workspace and never shared with another customer. We don't sell your data or make money from it. | Instantly's operator, Foo Monk, LLC, is on California's public data broker register. |
