Which option fits your team?
On small screens, scroll the table sideways.
| Your requirement | Where to start | What to check |
|---|---|---|
| Small campaign with an existing verified list | Compare Growth and Base | Base stores more contacts, but does not include CRM access or prospect data by default. |
| 25,000 contacts and up to 90,000 emails/month | Compare Hyper Growth and Pro | Both named limits cover that workload; price data, infrastructure and required extras. |
| 25,000 contacts and 100,000 emails/month | Inspect Hyper Growth or a higher Smartlead configuration | Pro's 90,000-send limit does not cover this example. |
| Autonomous reply coverage is essential | Inspect Instantly's Reply Agent; ask Smartlead to show equivalent scope | Test actual automation rather than treating AI drafting as automatic sending. |
| Separate client environments | Quote the required workspaces | Confirm access boundaries and recurring client charges, not just a platform's agency label. |

Monthly USD prices and named limits checked 8 October 2026; annual discounts and customised volumes differ. Uploaded or stored contacts are not newly sourced leads. Unlimited storage does not mean unlimited sends, prospect data or guaranteed inbox placement. Confirm the final plan selector and quote.
Which is cheaper at the entry level?
The displayed sending subscriptions differ by US$8/month: US$47 minus US$39. That comparison assumes you already have the contacts and required sending infrastructure. Instantly Growth plus Growth Credits is US$94/month before other costs. Request Smartlead's data add-on and inbox charges for the same workload before comparing a complete budget. A lower sending price does not establish lower cost per qualified opportunity.
Count follow-ups, not just new prospects
For a proposed audience of 1,000 contacts receiving an initial email and two follow-ups, the maximum scheduled workload is 3,000 emails before replies and exclusions reduce it. That arithmetic fits both named entry send caps, but leaves Instantly at its stated contact cap. A larger list may require a plan change even if the campaign sends few messages. Storage and monthly activity solve different constraints.
A bigger tier is not bigger in every dimension
The next named tiers have opposite advantages: Smartlead Pro stores more contacts, while Instantly Hyper Growth has a larger monthly send allowance. In a proposed 25,000-contact, four-message sequence, the maximum is 100,000 emails. That fits Hyper Growth's named limits but exceeds Pro's 90,000 sends. Spread timing or get an appropriate higher configuration rather than assuming a similar subscription price buys the same capacity.
Separate an AI reply draft from an autonomous response
Smartlead's reviewed Master Inbox instructions show selecting a lead, generating text, inserting it and pressing send. This establishes an assisted workflow, not the absence of other automation. Instantly documents reply-agent review, with Autopilot restricted to Hyper Growth and above. Ask both vendors to demonstrate your required mode and escalation path. Keep a wrong research claim and a nonstandard discount request unsent until the responsible person resolves them.
Before switching between Instantly and Smartlead
Export exclusions, reply state, contact identifiers and campaign history where supported. Map the current conversation owner and remove migrated records from the old active campaign before enabling the new one. Test a duplicate, a stopped sequence and a reply arriving during migration. Reconcile the two platforms before expanding; rebuilding a contact list without its stop state can restart unwanted follow-up.
Measure the result without inventing a deliverability winner
Run a controlled pilot with comparable audiences and the same offer. Track bounces, useful replies, meetings held, manual corrections and complete spend. Confirm which analytics counts exclude automated replies. Warmup availability and a monthly send cap do not prove delivery into a prospect's inbox. No head-to-head product test or independent deliverability result is claimed here.
Common buying questions
Is Smartlead cheaper than Instantly?
Its displayed Base sending subscription starts lower: US$39 versus US$47/month. Complete cost depends on the plan limits, prospect data, inboxes, CRM and optional services required for the same workflow.
Does unlimited mean unlimited cold emails?
No. Read the unit. Smartlead Unlimited Smart lists unlimited contact storage with a named 150,000 monthly send allowance. Instantly's connected-account provision does not remove monthly campaign or contact limits.
Which is best for an agency?
Inspect client isolation, access roles, reply ownership, exports and the full workspace quote. Neither is an agency winner from a feature list; demonstrate the required boundary between two clients before buying.
