Autoklose vs Instantly 2026: Which Wins on Deliverability?

Autoklose runs $59.99 to $99.99 per user per month across three tiers and doesn't publish contact limits or a warmup feature on its own site. Instantly starts at $37/month with unlimited sending inboxes, built-in warmup, and a 450M+ contact database baked into every plan. For teams sending 500+ emails a week, that gap in transparency and included infrastructure adds up fast.

Autoklose vs Instantly: Pricing and Features at a Glance

How Much Does Autoklose Cost vs Instantly in 2026?

Autoklose's three tiers run $59.99 to $99.99 per user per month, per pricing listings from Tekpon and SalesRobot, since Autoklose's own site doesn't post rates. Instantly's three tiers run $37 to $286 per month with every contact and send limit published upfront.

• Autoklose Starter: $59.99/user/mo
• Autoklose Advanced: $69.99/user/mo
• Autoklose Accelerated: $99.99/user/mo
• Instantly Growth: $37/mo (1,000 contacts, 5,000 sends)
• Instantly Hypergrowth: $77/mo (25,000 contacts, ~100,000 sends)
• Instantly Lightspeed: $286/mo (100,000+ contacts, 500,000+ emails)

A 3-person team on Autoklose pays for three seats even if only one person runs outbound, since pricing is per user. Instantly prices by sending volume, so a solo founder and a 3-person team on the same list pay the same rate.

Which Platform Handles Deliverability and Warmup Better?

Instantly built its product around inbox warmup, bundling unlimited warmup into every tier, including the $37/mo Growth plan. Autoklose markets itself as a sequencing and CRM-sync tool first, and none of its accessible pricing or feature pages advertise an automated warmup network.

Skip warmup and a fresh domain can land in spam within the first week, killing reply rates before a sequence finishes. For agencies managing 10+ client domains at once, that gap is the difference between a campaign that books meetings and one that never leaves Promotions.

Who Has the Bigger Contact Database, Autoklose or Instantly?

Instantly bundles a 450M+ B2B contact database into every plan tier, so a $37/mo Growth subscriber gets the same list access as a $286/mo Lightspeed account. Autoklose ships an in-app prospect database too, but no source we checked, including its own marketing pages, discloses a contact count.

For founders sending under 1,000 contacts a month, this gap barely matters since most teams bring their own list. For teams sourcing net-new accounts inside the tool, Instantly's published number is the only one you can actually plan a budget around.

Autoklose vs Instantly: Which Should You Pick?

Pick Instantly if you want published pricing, unlimited warmup, and a built-in contact database without a sales call. Pick Autoklose if your team already runs Salesforce and wants sequencing tied to a per-seat CRM sync, and you're comfortable requesting a quote for the real number.

• Sending 500+ emails a week and scaling fast: Instantly avoids Autoklose's per-seat tax.
• Agencies with 10+ client domains: Instantly's unlimited warmup and sending accounts remove a per-seat line item.
• Locked into Salesforce workflows already: Autoklose's CRM sync may justify the premium.

Autoklose's quote-based model is the exception in a market where Instantly, Smartlead, and Lemlist all show pricing without a call. Modern Inbound has booked 3,000+ qualified B2B meetings running outbound through platforms like these.

Frequently Asked Questions

Is Autoklose or Instantly better for cold email in 2026?

Instantly is the better fit for most teams because it publishes exact pricing, bundles unlimited warmup, and includes a 450M+ contact database on every plan. Autoklose fits teams already committed to Salesforce-based sequencing who don't mind requesting a quote.

Does Autoklose have email warmup like Instantly?

Autoklose doesn't advertise a standalone automated warmup feature on its public pages. Instantly bundles unlimited warmup into every plan starting at $37/month, which matters most for teams sending from newly registered domains.

How many contacts does Instantly's database include?

Instantly includes a 450M+ B2B contact database on every plan tier, from the $37/mo Growth plan up to the $286/mo Lightspeed plan. Autoklose ships a prospect database too, but doesn't publish a contact count on its marketing site.

Can you switch from Autoklose to Instantly without losing sequences?

You'll need to rebuild sequences manually since the platforms don't offer native migration. Export your Autoklose lists and sequence copy, then rebuild steps inside Instantly's campaign builder, usually a few hours of work.

Autoklose and Instantly both assume you already have the domains, copy, and targeting figured out. If you'd rather not run that experiment solo, that's what Modern Inbound's setup engagement handles end to end.
