Analysis
Where Instantly is strong
Instantly is excellent at warming sender domains, managing sending infrastructure, and running high-volume email sequences. If you have a large list and a human to write sequences, it sends reliably.
Where Instantly falls short
Instantly doesn't research prospects. It doesn't write personalized messages. It doesn't call. It doesn't handle replies. You still need a human SDR (or a team of them) to operate the tool and produce the output.
Bottom line
Instantly is a sending tool. Strides is an AI that does the full SDR job. The right question is: do you want infrastructure for your SDR team, or do you want to replace the SDR function entirely?

Deep Dive: Strides vs Instantly
Prospect Research
Instantly: You provide the list — Instantly sends to whatever list you upload. Research, ICP filtering, and prospect qualification are your responsibility.
Strides: AI researches every prospect — Strides monitors 47 signals to identify your ICP, researches each prospect in real time, and triggers outreach at the optimal moment — without a list.
Message Writing
Instantly: Human-written templates — You write the sequence. Instantly delivers it. Personalization is limited to merge tags — {{first_name}}, {{company}} — not genuine research-based personalization.
Strides: AI writes each email uniquely — Every email Strides sends is unique, grounded in real-time research about that specific prospect's company situation — not a template with a name tag.
Phone Outreach
Instantly: Email only — Instantly is an email platform. There is no AI calling capability included.
Strides: AI phone calls included — Strides makes real AI phone calls that follow up on email outreach, handle conversations, and book meetings on the call.
Reply Handling
Instantly: Manual reply management — When a prospect replies, a human reads and responds. Instantly has some basic sentiment detection but no autonomous reply handling.
Strides: Autonomous reply handling — Strides reads every reply and responds appropriately — handling objections, routing genuine interest to meeting booking, and managing opt-outs — all without human involvement.
Pricing
Instantly: From $37/month — Instantly starts low, but you still need human SDRs to operate it — adding $60–90K per SDR in headcount costs not reflected in the tool price.
Strides: Full SDR function included — Strides replaces the SDR — the tool price is the total cost, without the headcount.
A Sending Tool vs. A Sales Rep
Instantly optimizes the email delivery layer of the SDR function. Strides replaces the SDR function entirely. The difference is everything that happens before the email is sent and after the reply arrives.
Instantly needs a human to run it. Strides runs itself.
Pricing: Instantly vs Strides
Instantly Growth: $97/mo — Plus $60–90K per SDR to operate it
Strides Growth: $299/mo — Full SDR function — no additional headcount

Who should switch from Instantly to Strides?

Who should stay on Instantly?
Companies with large in-house SDR teams who prefer to control every aspect of message writing and have Instantly as their preferred sending infrastructure.
Frequently Asked Questions
Can I import my Instantly contact lists into Strides?
Yes. Export your contacts from Instantly as CSV and import them as a campaign list in Strides. Strides will research each contact further and personalize outreach before sending.
Does Strides have better deliverability than Instantly?
Instantly is specifically engineered for deliverability at volume — domain warming, inbox rotation, sending throttling. Strides' deliverability is excellent but if you're sending 1,000+ emails per day to cold lists, Instantly's infrastructure focus is worth noting.
Can I use both Strides and Instantly together?
You can, but it's redundant. Strides provides its own sending infrastructure. Most customers that switch to Strides cancel Instantly because there's no need for both.
Does Strides have email sequence functionality like Instantly?
Yes. Strides runs multi-touch email sequences. The difference is that Strides writes each sequence email dynamically based on prospect research, whereas Instantly executes fixed sequences written by humans.
Is Strides more expensive than Instantly overall?
No — when total cost of outbound is accounted for. Instantly requires human SDRs to operate it. Strides doesn't. Total cost of outbound with Strides is 80–95% lower than Instantly + SDR headcount.
