Instantly

Instantly and Smartlead are the two leading volume cold email platforms and very similar in core functionality: unlimited inbox connections, unlimited warmup, and agency-friendly pricing. Instantly wins on AI features (better AI-assisted sequences, AI-powered CRM) and the SuperSearch built-in lead database. Smartlead wins on price (Base at $39/mo vs. Growth at $37-$47/mo but with fewer features at entry) and master inbox management at larger scale. Most agencies pilot both before committing — the choice often comes down to UX preference rather than feature gaps.

The advertised Growth plan is $37/month, but that does not include the SuperSearch lead database. SuperSearch lead credits run $9/month for 150 leads up to $197/month for 10,000 leads. A realistic fully loaded Instantly setup with leads, moderate CRM usage, and a few sending domains typically runs $150-$400/month depending on volume. Factor this in when comparing to Lemlist or Reply.io where the advertised price is closer to the real price.

Unlimited on every paid plan. This is Instantly's defining feature and why agencies and high-volume senders pick it. You can connect hundreds of Gmail, Outlook, and custom SMTP inboxes under a single subscription, rotate sends across them for deliverability, and manage all replies in the unibox. Smartlead offers the same unlimited connection model; most other cold email tools (Lemlist, Reply.io) meter you on seats or add extra cost per connected inbox.

Yes, and it is one of the most robust in the industry. Instantly's warmup network simulates real human email activity between Instantly users — senders, replies, marks-as-important — to boost sender reputation on new or cold inboxes. Warmup is unlimited and free on every paid plan. Most serious cold email operators run warmup for 2-4 weeks on any new sending domain before launching campaigns to maximize inbox placement.

No. Instantly is email-only. It does not support LinkedIn connection requests, messaging, or profile views, and it does not include a cold calling dialer. If you want multichannel outreach across email + LinkedIn + calls, look at Lemlist Multichannel Expert ($99/user/mo), Reply.io Multichannel ($89/user/mo), or Amplemarket. Many sales teams use Instantly for email at scale and a separate tool like Dripify or Waalaxy for LinkedIn automation.

SuperSearch is Instantly's built-in B2B lead database, launched as an add-on to reduce the need for external prospecting tools like Apollo or ZoomInfo. SuperSearch lets you search contacts by role, company, industry, and firmographic filters, enrich with verified emails, and push leads directly into Instantly campaigns. Pricing is separate from the base plan: $9/month for 150 leads scaling to $197/month for 10,000 leads. Lead quality is acceptable for mid-market B2B but not as strong as Apollo or ZoomInfo for niche segments.

Instantly is GDPR compliant, provides DPA on request, and supports opt-out handling and unsubscribe management required for compliant cold email. Like all cold email tools, final compliance depends on how you use it — sending cold email to EU contacts without a legitimate interest basis is a violation regardless of tool. US-based senders targeting US contacts generally have fewer concerns. For strict EU-to-EU cold outbound, Lemlist's native EU hosting and France-based compliance posture is a stronger fit.
