BIGM vs Instantly
An honest side-by-side from the team that built BIGM. We use Instantly ourselves; this page tells you when to pick them over us, and the specific cases where the BIGM architecture is structurally better.
Your bottleneck is cold email at high volume — inbox rotation, warm-up, deliverability. Instantly is excellent at this and the price point makes it a no-brainer for cold-email-first teams.
You want more booked meetings from LinkedIn outbound — and you're already happy with your cold email setup. BIGM applies the pool-rotation playbook to LinkedIn accounts that Instantly applies to email inboxes, with the outcome metric being meetings booked, not just inbox deliverability.
What Instantly does well
Cold email platform with strong inbox rotation, warm-up, and deliverability tooling. Newer entrant that grew fast on the back of the inbox-rotation play (route sends across many secondary inboxes to protect the primary).
Pricing: Tiered SaaS, roughly $30-$77/user/month for the standard plans, enterprise custom. Aggressive on entry price relative to Lemlist + Apollo.
- Cold email at scale where the bottleneck is deliverability + inbox rotation
- Lean teams that want the inbox-rotation + warm-up infrastructure without paying for a database
- Senders who run cold email volumes that single-inbox setups can't sustain
Where BIGM is structurally better
BIGM isn't a "Instantly replacement" in the generic sense. It's a LinkedIn-outbound specialist with a pool architecture built for restriction-resistance + reply-rate optimization. Specifically:
- Your channel is LinkedIn outreach, not cold email (Instantly's strength doesn't apply to LinkedIn)
- You've solved cold email deliverability already and your gap is on the LinkedIn side
- Restriction risk is the conversation, not deliverability
- You want the same operating logic (rotate across a pool) applied to LinkedIn specifically
