Instantly is one of the best-known cold email platforms in the world, and the reason is simple: it solved sending. Unlimited mailboxes, warm-up, rotation, volume. If your entire outbound motion lives in the inbox, that is a real advantage.
Prosyo vs Instantly comes down to one question: is email your only channel? Instantly has no LinkedIn automation. Prosyo runs LinkedIn and email as steps in the same sequence, against the same prospect, with one inbox for both replies. If half your pipeline comes from LinkedIn — and for most founders, consultants and agencies selling to a professional audience, it does — an email-only platform leaves that half unautomated.

Prosyo vs Instantly: the quick verdict
Choose Instantly if you send cold email at volume across dozens or hundreds of mailboxes, you have no LinkedIn motion, and mailbox infrastructure is the constraint holding you back. That is what Instantly is built for and it is good at it.
Choose Prosyo if you want LinkedIn and email running as one motion — connection request, then message, then email, then follow-up, all stopping the moment someone replies — with enrichment, intent and pipeline in the same product. Prosyo starts at $19/month, and multichannel with both LinkedIn and email is $49/month.

Prosyo vs Instantly pricing, side by side
| Prosyo | Instantly | |
|---|---|---|
| Entry plan | $19/month (Starter) — LinkedIn outreach, 1 LinkedIn account | $37/month (Growth) — email only, 5,000 emails/month |
| Multichannel plan | $49/month — LinkedIn + email in one sequence | $97/month (Hypergrowth) — still email only, 25,000 emails/month |
| Agency / team plan | $49 per seat per month, minimum 2 seats | $358/month (Light Speed), 100,000 emails/month |
| Annual pricing | $173.28/year Starter, $446.88/year Multichannel | Discounted annual available on each tier |
| Lead data | Enrichment included in the product, paid by credit | Lead database is a separate subscription, roughly $47–$197/month |
| CRM / pipeline | 6-stage pipeline included on every plan | Instantly CRM is a separate line item, around $47/month |
| Realistic monthly cost for a full outbound stack | $49 — LinkedIn, email, enrichment credits, inbox, intent, pipeline | $200–$400 once lead data and CRM are added, and still no LinkedIn |
| Free trial | 7 days, no card, 25 AI credits | Free tier and paid trial options |
| Payment | Cards, plus INR and UPI with GSTIN invoicing | Card |
The number that matters is the bottom row. Instantly’s $37 entry price is real, but it buys sending only. Add the lead database to find anyone and the CRM to track them and you are at $200–$400 a month for a stack that still cannot send a LinkedIn connection request. Prosyo’s $49 Multichannel plan covers both channels, the enrichment, the inbox and the pipeline in one line item.
Feature-by-feature: Prosyo vs Instantly
| Area | Prosyo | Instantly |
|---|---|---|
| LinkedIn automation | Native. Connection requests, messages, InMail-style follow-ups, profile views and old invites cleared automatically. | None. Instantly does not automate LinkedIn. |
| Email outreach | Included on Multichannel and Agency plans, sequenced alongside LinkedIn steps. | The core product. Unlimited mailboxes, warm-up, rotation, high volume. |
| One sequence, both channels | Yes. 9 step types mixing LinkedIn and email actions against the same prospect. | No. Email sequences only. |
| Unified inbox | LinkedIn and email replies in one inbox, replies sorted automatically, voice notes inline, answers drafted for you. | Email replies only. |
| Account safety | Safe by default, nothing to configure — human pacing with natural gaps between actions. | Email sending limits and warm-up; no LinkedIn limits to manage because there is no LinkedIn. |
| Stop on reply | On by default, across both channels. | Available for email sequences. |
| Enrichment | Built in and charged per credit. Emails and phones verified before delivery, returned above 89% confidence, and not charged below that. | Separate lead database subscription. Reviewers consistently report outdated addresses, wrong titles and elevated bounce rates on raw exports. |
| Intent signals | Intent Today, grouped into Asking, Evaluating you, Moment of need and Coming back. | Not part of the core product. |
| Pipeline | 6 stages: New → Contacted → Replied → Interested → Meeting → Customer. Included. | Instantly CRM, sold separately. |
| Voice notes | Recorded and sent inline from the inbox. | Not applicable to email. |
| What a credit buys | 1 credit per AI draft, 1 per AI summary, 40 free drafts a day before credits are used. Enrichment charged per verified record only. | Credit model introduced in the 2025 migration; several reviewers report confusion and incorrect deductions. |
| Imports | 5 sources, including CSV and the Chrome extension “Prosyo: Book Meetings on Autopilot”. | CSV, API, lead database. |
| MCP / AI agent access | Free on every plan, no credits consumed. | API access by plan. |
Where Instantly is genuinely strong
This is not a straw man. Instantly holds a 4.8/5 average across more than 3,400 G2 reviews, and the praise is specific and deserved:
- Mailbox infrastructure at scale. Unlimited email accounts on outreach plans, with rotation handled for you. If you are running 50 or 200 mailboxes, very few products make that as painless.
- Warm-up. The warm-up network is large and it is the feature reviewers rate highest.
- Volume economics. At 100,000 emails a month, $358 is a defensible per-send cost.
- Campaign builder and UI. Consistently rated as easy to learn.
If your outbound is a pure cold email play and LinkedIn is not part of your motion, Instantly is a reasonable choice and Prosyo is not trying to talk you out of it.
What Instantly customers actually say
The 4.8 on G2 sits alongside a 3.8/5 across nearly a thousand Trustpilot reviews, and the gap is where the useful information lives. Four themes repeat across independent review roundups:
Warm-up scores that do not match real inbox placement. Reviewers describe healthy-looking warm-up dashboards while live campaigns land in spam, because the dashboard reflects activity inside Instantly’s own warm-up pool rather than actual placement at the recipient’s provider. One reviewer’s summary: “Test emails went to spam even after waiting weeks for warmup.”
No diagnostic path when deliverability breaks. Users report “random bounce spikes with no explanation or alerting” — no root-cause data and no alerts when performance drops.
Lead database accuracy. Outdated email addresses, incorrect job titles and elevated bounce rates from raw database exports are documented across reviews, with many users paying a second data provider on top.
Domain ownership on the done-for-you service. This is the one to read carefully before you sign. Domains set up through Instantly’s done-for-you infrastructure service are retained by Instantly, and reviewers report resistance when trying to use those domains with another tool or move off the platform.

The structural difference: one channel versus two
Every other difference on this page follows from one fact. Instantly automates email. Prosyo automates LinkedIn and email against the same person, in the same sequence.
That is not a feature-count argument, it is an operating-model argument. In an email-only stack, a prospect who ignores three emails is dead. In Prosyo, that prospect gets a connection request on day 5, a LinkedIn message on day 8 if they accept, and the email thread continues in parallel — and the whole sequence stops the moment they answer on either channel, because stop-on-reply is on by default and covers both.
The alternative is to buy Instantly for email and a separate LinkedIn tool, then reconcile them by hand. You now run two prospect lists, two inboxes, two sets of limits, and no reliable way to stop the email sequence when someone replies on LinkedIn. That reconciliation is the work Prosyo removes.
1. LinkedIn and email in one sequence
Nine step types — connection requests, LinkedIn messages, profile views, emails, follow-ups, delays, conditions — built into a single sequence against a single prospect record.
2. One inbox for both channels
LinkedIn and email replies land together, sorted automatically, with voice notes inline and answers drafted for you.
3. Enrichment that does not bill you for guesses
Emails and phones are verified before delivery, returned only above 89% confidence, and not charged below it. That is the opposite of a raw database export you pay for and then bounce.
4. Safe by default
Safe by default, nothing to configure. Prosyo paces every LinkedIn account like a careful human, sends only in business hours, and goes quiet the moment someone replies.
5. Intent, grouped by what it means
Intent Today sorts signals into Asking, Evaluating you, Moment of need and Coming back — so you know why an account surfaced, not just that it did.
6. Pipeline included
Six stages from New through Contacted, Replied, Interested and Meeting to Customer, on every plan. No separate CRM subscription.
Which is better for…
High-volume cold email agencies. Instantly, if email is genuinely the whole motion. Its mailbox handling at 50+ inboxes is stronger than anything Prosyo offers, because Prosyo is not trying to be a mailbox infrastructure product.
Founders doing their own outbound. Prosyo. At $19/month you get LinkedIn outreach from your own profile — which is where a founder’s credibility actually lives — and $49 adds email on top. Instantly’s equivalent stack starts at $37 and cannot touch LinkedIn.
Agencies running client outbound. Prosyo, at $49 per seat with a two-seat minimum, gives each client their own LinkedIn identity and email accounts under one roof. Instantly gives you shared mailbox infrastructure and a separate CRM bill.
Consultants and service businesses. Prosyo. When your buyer is a person rather than a role inbox, LinkedIn is usually the higher-reply channel, and an email-only tool cannot reach them there.
Teams already burned by deliverability. Worth considering Prosyo specifically because LinkedIn gives you a channel that is not subject to spam filtering at all, so one bad domain reputation does not take your whole pipeline down.
Switching from Instantly to Prosyo
- Check your domain ownership first. If you used Instantly’s done-for-you infrastructure, confirm which domains and mailboxes are registered to you before you plan a move. This is the single most common surprise in an Instantly migration.
- Export your lists and suppressions. Take your prospect lists, your do-not-contact list and your reply statuses. The suppression list matters most — re-contacting someone who already said no is the expensive mistake.
- Import into Prosyo. Five import sources, including CSV and the Chrome extension. Enrichment can fill the gaps, verified and charged only above 89% confidence.
- Connect both channels. Connect your LinkedIn profile and your email accounts, and Prosyo eases a LinkedIn account that has not run automation before in gently — nothing to set.
- Rebuild one sequence, not all of them. Take your best-performing Instantly email sequence and add the LinkedIn steps around it rather than porting everything. Run it for two weeks against the old one and compare reply rates per channel before you migrate the rest.

The final recommendation
If you run cold email at serious volume and nothing else, Instantly is a strong product and its reputation is earned. Buy it with your eyes open on two things: the warm-up dashboard is not a placement guarantee, and the done-for-you domains may not be yours.
If LinkedIn is part of how you sell — or you suspect it should be — an email-only platform is a structural limit no amount of warm-up fixes. Prosyo runs both channels in one sequence, with one inbox, verified enrichment, intent and pipeline included, starting at $19/month and $49 for full multichannel. For most founders, consultants, agencies and lean sales teams, that is both the cheaper stack and the one that reaches people where they actually reply.
Frequently asked questions
Does Instantly do LinkedIn outreach?
No. Instantly is an email-only platform. It does not send LinkedIn connection requests or messages. Teams that want both channels either buy a second LinkedIn tool and reconcile the two by hand, or use a multichannel platform like Prosyo where LinkedIn and email steps sit in one sequence.
Is Prosyo cheaper than Instantly?
Yes, once you compare the full stack. Prosyo starts at $19/month and full multichannel is $49/month, including enrichment credits, unified inbox, intent and pipeline. Instantly starts at $37/month for email sending alone; adding its lead database ($47–$197/month) and CRM (around $47/month) typically brings real-world spend to $200–$400/month — and still without LinkedIn.
Why is Instantly rated 4.8 on G2 but 3.8 on Trustpilot?
The gap is common and informative. G2 tends to capture users at the point of satisfaction; Trustpilot captures a broader set, including billing disputes and exits. The recurring Trustpilot themes are the 2025 credits migration, support responsiveness on complex accounts, and domain ownership on the done-for-you service.
Can I keep my domains if I leave Instantly?
It depends how you got them. Domains you registered yourself and connected are yours. Domains provisioned through Instantly’s done-for-you infrastructure service are retained by Instantly, and reviewers report friction when trying to move them. Check this before you migrate, not after.
Is Instantly’s lead database accurate?
Reviewers consistently report outdated addresses, wrong job titles and elevated bounce rates on raw exports, with many users paying for a second data provider. Prosyo takes the opposite approach: enrichment is charged per credit, records are verified before delivery, returned only above 89% confidence, and you are not charged for anything below that threshold.
Which is better for deliverability?
For pure email volume, Instantly’s warm-up network is larger and that is its strongest-rated feature. The caveat from its own user base is that the warm-up score reflects activity in Instantly’s pool rather than real inbox placement. Prosyo’s answer to deliverability risk is structural rather than infrastructural: LinkedIn is a second channel that spam filters do not touch, so a domain problem does not take your entire pipeline with it.
Can agencies use Prosyo instead of Instantly?
Yes. Prosyo’s Agency plan is $49 per seat per month with a two-seat minimum, giving each client their own LinkedIn identity and email accounts, with pipeline and inbox included. Agencies running very large mailbox fleets purely for cold email will still find Instantly’s infrastructure stronger for that specific job.
Does Prosyo offer a managed option?
Yes. Prosyo also runs Managed ABM + AI SDR for teams that want ICP work, target-account research, campaign setup, personalization, LinkedIn and email execution, reply handling and qualification done for them.
