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.
Your bottleneck is LinkedIn outreach — restriction risk, account pool orchestration, per-prospect message quality. The pool-rotation playbook Instantly applies to email inboxes, BIGM applies to LinkedIn accounts.
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
