Smartlead’s API and webhooks start at Pro ($94), not Base ($39). Smartlead’s pricing page states that Base does not include them. Any Make.com workflow with Smartlead therefore starts at Pro. Verified prospect emails are also a $59 monthly add-on on Base and Pro.
Apollo and the senders are not the same kind of product. Apollo’s per-seat price includes a database and sales platform, so five users on Professional cost about $395 a month. Smartlead and Instantly charge a flat fee for sending capacity, no matter how many people use them.

Smartlead vs Apollo
Verdict: they are different layers. Use Apollo to find leads and Smartlead to send to them.
- Choose Apollo if prospect data, enrichment and a single all-in-one tool matter most.
- Choose Smartlead if you need many mailboxes, high volume, warmup and white-label for clients. Every Smartlead plan includes unlimited email accounts, while Apollo caps mailboxes by plan.
- Cost trap: Apollo grows with every seat; Smartlead stays flat as your team grows.
Instantly vs Apollo
Verdict: same split. Apollo for data, Instantly for email-first sending.
- Instantly gives unlimited email accounts from $47 a month, with webhooks on Hypergrowth and above.
- Apollo can send too, but its mailbox limits are plan-based, so high-volume teams often add a dedicated sender.
- Our take: if you pick Instantly as the sender, Apollo is still the data layer. We have no Instantly referral link, so this page doesn’t earn from that choice.
Smartlead vs Instantly
Verdict: close. Smartlead edges ahead for agencies and infrastructure; Instantly suits simpler email-first teams.
- Entry price: Smartlead $39 vs Instantly $47. For API access, Smartlead needs Pro ($94) and Instantly needs Hypergrowth ($97).
- Capacity: both list 500,000 emails a month at the top tier.
- Agencies: Smartlead offers client workspaces and white-label; Instantly does not lead on this.
Apollo Data and API Model
Apollo’s People API Search finds prospects but does not return email addresses or phone numbers. Enrichment is a separate step, and credit usage varies by endpoint. Apollo’s rate limits are team-level, with minute, hour and day windows, so build in pagination and retries.
API and Webhook Automation with Make.com
Smartlead’s campaign lead endpoint accepts up to 400 leads per request. A minimal payload:
{
"lead_list": [
{
"email": "{{email}}",
"first_name": "{{first_name}}",
"last_name": "{{last_name}}",
"company_name": "{{company_name}}",
"custom_fields": { "apollo_id": "{{apollo_id}}" }
}
]
}Match the fields to Smartlead’s current API documentation. Don’t copy undocumented parameters from older tutorials. Instantly’s API v1 was deprecated in January 2026, so use v2 there.
Domains, Authentication and Tracking
No platform can guarantee inbox placement. Reputation, content, complaint rates and authentication all matter. For senders at 5,000 or more messages a day to Gmail, Google requires SPF, DKIM and DMARC, valid DNS, TLS and low spam rates, plus one-click unsubscribe for marketing mail.
- Warmup: there is no universal “14 days and you’re ready” rule. Ramp gradually and watch bounces and complaints.
- Custom tracking domain: both Instantly and Smartlead document it. It removes a shared tracking-URL dependency but doesn’t guarantee placement.
- Separate sending domains: useful for some teams, but add configuration and monitoring work. Decide based on your compliance and reputation needs.
Common Mistakes When Choosing
- Treating Apollo as “just a database”. It includes sequencing, CRM, workflows and AI features.
- Assuming Smartlead’s $39 plan includes API access. It starts at Pro.
- Comparing Apollo’s per-seat price directly with flat sending plans.
- Expecting warmup or dedicated infrastructure to guarantee inbox placement.
- Skipping Apollo’s enrichment step and credit costs when planning automation.

Frequently Asked Questions
Is Smartlead better than Instantly?
For agencies and API-driven outbound, Smartlead has the edge with client workspaces and white-label options. For a simple email-first tool, Instantly is a legitimate alternative. Both list roughly 500,000 monthly emails on their top plans.
Is Apollo only a lead database?
No. Apollo combines prospect data and enrichment with sequencing, CRM features, workflows and AI tools, though data is the main reason most teams buy it.
Can Apollo send cold email without Smartlead or Instantly?
Yes, Apollo includes sequencing and sending. Teams separate the layers when they need more mailboxes, higher volume or external automation.
Can Apollo connect to Smartlead through Make.com?
Yes. Use Apollo’s API for search and enrichment, Make for mapping and routing, and Smartlead’s campaign API to load leads. Smartlead’s API requires the Pro plan or above.
Does Smartlead have an API and webhooks?
Yes, from the Pro plan up. Smartlead’s pricing page states the Base plan does not include API and webhooks.
Does Instantly have webhooks?
Yes. Instantly’s documentation says webhooks are available on Hyper Growth and above.
How long should a new cold-email domain warm up?
There is no universal duration that guarantees inbox placement. Introduce a new sender gradually, authenticate the domain and increase volume only as bounces and complaints stay low.
Do custom tracking domains improve deliverability?
They remove a shared tracking-domain dependency, but they don’t guarantee inbox placement because reputation, content and recipient behavior still matter.
