Instantly vs QuickMail: Cold Email Platform Comparison

Instantly vs QuickMail: Cold Email Platform Comparison

These two agree on the thing most cold email platforms charge for: both give you unlimited sending accounts on every tier. What they disagree about is what the plan price should meter instead, and that disagreement is worth about a hundred dollars a month at the wrong volume.

The Quick Answer

Instantly meters uploaded contacts and monthly sends together: 1,000 and 5,000 on Growth at $47, 25,000 and 100,000 on Hypergrowth at $97, 100,000 and 500,000 on Light Speed at $358.

QuickMail meters uploaded contacts alone: 1,000 on Starter at $49, 25,000 on Growth at $99, 100,000 on Agency at $299, with unlimited email senders, unlimited LinkedIn accounts and unlimited users throughout.

The ladders are strikingly close at the bottom and diverge at the top, where QuickMail buys workspaces and Instantly buys send volume.

Understanding the Core Difference

Instantly is a cold email platform built on unlimited email accounts and unlimited warmup at every tier, with the plan price set by uploaded contacts and monthly sends.

QuickMail is a cold email platform built for agencies and high-volume senders, with unlimited email senders, unlimited LinkedIn accounts and unlimited users on every tier.

Instantly's tiers pair a contact allowance with a send allowance, which is a tighter constraint than a contact cap alone: a three-touch sequence to a list consumes the send allowance three times as fast as a single-touch campaign does. Unlimited email accounts and unlimited warmup sit on every tier.

QuickMail's tiers climb on uploaded contacts and give the rest away. Users, senders and LinkedIn accounts never move the price, so a ten-person agency running fifty mailboxes pays the same as a solo operator with the same contact count. Workspaces are the agency lever: Agency at $299 includes two, with extras at $49 each.

Both are unusually well shaped for cold outbound, which is why this comparison turns on billing shape rather than on capability.

Instantly pricing

Unlimited email accounts and unlimited email warmup are included on every tier, which is the feature that decides most Instantly comparisons. Note the page now leads with bundles that pair an Outreach plan with a credits plan, so a quoted Instantly price may be a bundle rather than the sending plan alone.

QuickMail pricing

Unlimited email senders, unlimited LinkedIn accounts and unlimited users are listed on all three tiers, so the price ladder is bought with contact volume rather than with seats or mailboxes.

What the two cost at a realistic volume

Take an invented but ordinary case: an agency running four clients, 30,000 contacts a month in total, forty mailboxes, one message per prospect. The arithmetic is illustrative and uses list prices only.

On QuickMail, 30,000 contacts is above Growth's 25,000 so the plan is Agency at $299, which includes two workspaces; four clients means two more at $49 each, for $397 a month, with the forty mailboxes and every user free.

On Instantly, 30,000 contacts and 30,000 sends sits between Hypergrowth's 25,000 contacts and Light Speed's 100,000, so the plan is Light Speed at $358, with 500,000 sends of headroom the agency will not use. Client separation is handled by workspaces rather than by the plan.

Shrink it to one client, 4,000 contacts and twelve mailboxes: QuickMail Starter's 1,000-contact cap fails, so it is Growth at $99, against Instantly Growth's 1,000-contact cap failing too, putting it on Hypergrowth at $97. At that size they are a coin toss.

Reading the price ladders against each other

The entry prices are $47 and $49 and the first ceilings are both 1,000 contacts, which makes the bottom of these two ladders almost interchangeable.

Where they part is the middle and top. Instantly's send allowance is the number to model if your sequences are longer than one message, because it is consumed per send rather than per person. QuickMail's contact ladder is flatter and more predictable, and its Agency tier prices client separation explicitly.

Both discount annual billing; Instantly's rates drop to $37.6, $77.6 and $286.3.

The lists overlap more than in most comparisons in this category, which is the honest finding. Both do warmup, both rotate across unlimited senders, both handle replies centrally, both expose an API.

Two real differences. Instantly carries dedicated IP rotation on its top tier and unlimited warmup throughout. QuickMail includes unlimited LinkedIn accounts on every tier alongside the email senders, and puts API and webhook access on its higher tiers.

Integration Ecosystem

Instantly connects with: HubSpot, Salesforce, Pipedrive, Zapier, Make, n8n, Clay, Slack, Google Calendar.

QuickMail connects with: HubSpot, Pipedrive, Zapier, Make, Slack, Gmail, Outlook, Google Sheets.

Both tools integrate with: HubSpot, Pipedrive, Zapier, Make, Slack.

Both cover the CRMs most teams run and both expose an API, with QuickMail reserving webhook access for its higher tiers.

The practical difference is operational rather than integrational: QuickMail's workspaces and unlimited users make it easy to drop into an existing agency process, and Instantly's model is built around one team owning a large mailbox pool.

Who Should Pick Which

Pick QuickMail if you run client work. Workspaces, unlimited users and per-workspace pricing at $49 for extras are built for that shape, and Instantly's ladder charges you in send volume for the same separation.

Pick Instantly if sends outpace contacts. A programme with long sequences or heavy retargeting consumes sends faster than contacts, and Instantly's allowance is sized for that while QuickMail does not meter it at all.

Pick QuickMail if predictable pricing across a growing team matters. Only contact volume moves the bill, so the forecast is one number.

Pick Instantly if dedicated IP rotation is on the roadmap. It sits on the top tier and QuickMail has no equivalent.

Where each one sits in a cold outbound stack

Both fill the sender slot and both are unusually well shaped for it, because both give away the mailbox count.

Our own doctrine keeps that slot deliberately thin: one message per campaign, no bumps and no thread replies, and volume spread across many low-volume mailboxes so no single address carries too much. LinkedIn runs as its own motion rather than as a step inside an email sequence, because a second LinkedIn message lands under the one that was ignored and reads as a bump whatever the campaign structure says.

Under that doctrine the send allowance matters less than it would for a team running long sequences, which pushes the comparison toward QuickMail's flatter contact ladder. One note on QuickMail's unlimited LinkedIn accounts: they are worth having, and they are worth having for first-touch work rather than for retargeting anyone who ignored a message.

Switching between them

Both export prospects and campaigns to CSV, and neither carries sending reputation across.

Order of operations: suppression lists first, then re-authenticate the sending domains with SPF and DKIM confirmed on the new platform, then warmup, then a two to three week ramp. Rebuild copy in the new editor rather than pasting it.

Because both allow unlimited senders, this migration is unusual in not requiring new mailboxes. That makes it faster than most, and it also means the warmup restart is the whole cost, so do not skip it on the grounds that the addresses are already warm elsewhere.

Feature Comparison Summary

Getting Started Checklist

1. Count uploaded contacts and monthly sends separately. QuickMail prices the first, Instantly prices both.
2. Multiply touches per prospect by list size before checking Instantly's send allowance.
3. If you run client work, price QuickMail's workspaces against the alternative.
4. Check whether a quoted Instantly price is a plan or one of its bundles.
5. Send one real segment through each and read the replies.
6. Confirm suppression list export from whichever you pick.

Final Thoughts

This is one of the closest comparisons in the category, because both platforms already agree that mailboxes should be free. Decide two things: whether your sequences are long enough for a send allowance to bind, and whether you need workspaces.

Everything else is close enough that a trial on a real segment will tell you more than a feature table.
