Apollo vs Reply.io: sequencing and data in one

Apollo blocks the calls itself, then writes TCPA compliance back onto you

Apollo blocks calls to Do Not Call-listed numbers once screening is switched on, an opt-in setting, but its own contract still pushes TCPA and CAN-SPAM compliance onto the customer, and its email opt-out link is optional, can be toggled off, and expires after 47 days; Reply.io names no TCPA or calling provision at all, though it requires A2P 10DLC registration for SMS and honors STOP replies. Scope compared, criterion by criterion. Checked 7 September 2026.

Reply.io vs Apollo: scope compared, criterion by criterion — checked September 7, 2026
Reply.io	Apollo
What the tool answers
What it measures or produces
Outbound sales engagement platform: it runs multichannel sequences, finds leads, generates AI replies, and produces booked meetings plus campaign statistics.	Apollo produces verified B2B contact data — emails and phone numbers — plus outbound sequences, a dialer, and lead scores, all metered as credits per action.
The job it equips
Outbound sales teams — SDRs, AEs, prospecting agencies — with separate Multichannel, Agency multi-client, and autonomous AI SDR offerings.	The outbound SDR: account search, contact reveal, multichannel sequences, and outbound calling all live in one seat-based interface.
What it cannot tell you
Absent from the feature lists published at reply.io/pricing/ on 2026-09-02: any numeric per-tier daily sending cap, hosting region choice, and interface language list.	Apollo publishes aggregate monthly refresh volumes but never the verification date of any individual record, and none of those figures carries a publisher date.
Cold outreach
Channels covered
Native email, LinkedIn and calls/SMS as paid per-account add-ons, WhatsApp cited by the publisher, and any other channel wired into a sequence through Zapier.	Automated and manual email, calls via built-in dialer, LinkedIn and free-form tasks. LinkedIn steps are manual tasks to be completed, not automated sends.
Sending limits
Limits set by the user mailbox by mailbox, in emails per day and per minute. No numeric per-tier cap is published; a fair usage policy is invoked.	Apollo publishes no sending cap per pricing tier. It publishes recommendations: 50 to 100 emails per day per mailbox, 10 to 20 per hour.
Mailbox warm-up
Warmup included at no extra cost with every purchased mailbox, via a peer-to-peer network of real inboxes; a ramp-up raises the daily volume to the configured limit.	Available but not native: provided by a third party, Warmbox.ai. One mailbox per seat on paid plans; each additional mailbox costs 200 credits per 30-day period.
Personalization
AI variables for personalization at scale and multichannel conditional sequences. The publisher publishes no separate AI price on the outreach tiers.	Dynamic variables with nested conditional logic, comparators and case modifiers. AI research consumes one run per enrichment field, per saved contact.
Where the contacts come from
Built-in database advertised at over one billion global contacts, supplemented by CRM sync. Fifty live data credits per month on outreach tiers.	Three sources: the built-in database, file import, and a Chrome and Edge browser extension working on LinkedIn, Sales Navigator, Gmail, company websites and CRMs.
CRM synchronization
Salesforce natively two-way; HubSpot and Pipedrive two-way with an automatic sync session every two hours. Required tier not published.	Bidirectional sync with HubSpot, Salesforce or Pipedrive, one CRM connected at a time. The required tier is not named in the publisher's documentation.
Outbound compliance under US law
Email: an opt-out link ships by default but the customer can remove it; no non-compliant send is blocked. TCPA/calling is absent. SMS: A2P 10DLC required, STOP honored. The send window is user-set, not enforced.	Apollo blocks calls to DNC numbers once screening is on (opt-in), but pushes TCPA/CAN-SPAM onto the customer by contract. The email opt-out link is optional, toggleable off, and expires after 47 days. No SMS step exists at all.
What comes out of it
Export formats
CSV export of statistics is listed as a tier feature on the pricing grid. No other format (XLSX, PDF, non-API JSON) is named on that page.	The documented export format is CSV. The real ceiling is the record selection limit: 25 on Free, 1,000 on Basic, 2,500 on Professional, 10,000 on Organization.
API access
API v3: quota in requests, 100 per minute and 3,000 per hour, per user, Bearer token. Required plan tier not specified in the documentation.	Quota is counted in requests per minute, hour, and day, per team: 50/200/600 on Free, 200/400/2,000 on Basic and Professional, 200/600/6,000 on Organization.
What it connects to
Native integrations
Native CRMs Salesforce, HubSpot, Pipedrive, Copper, Zendesk Sell, Close; Twilio natively for calls and SMS; Zapier, Make, n8n for no-code.	The only publisher-stated count, “50+ tools,” appears in the marketplace page's meta description, not on the page itself. Salesforce, HubSpot, and Outreach matter most.
Google tools it connects to
Gmail mailbox connection via OAuth, alongside Office 365 and IMAP/SMTP; Google Calendar is integrated for meeting booking.	Per the grid, the Free plan connects Gmail and Microsoft mailboxes; paid plans accept all providers. A Gmail extension ships on all four plans.
Bringing your existing data across
Migration via bulk two-way CRM sync from Salesforce, pushing simultaneously into campaigns. CSV import exists but is not described on the pages consulted.	CSV import requires at least one of company name, website, LinkedIn URL, or email, and the publisher advises against files over ten thousand rows.
Getting started, and the fine print
Support
Live chat and email, stated response under fifteen minutes during operating hours 2 AM–7 PM EST. Language unspecified. CSM onboarding on higher tiers.	Basic email support covers all four plans; chat and priority email start at Basic; GTME expertise is reserved for the Organization plan.
Where the data is hosted
Processing in the United States of America and any other jurisdiction where the publisher or its sub-processors operate; the publisher itself warns the protection level may differ.	The United States. The DPA names outsourced US-based data center providers and frames transfers with the EU Standard Contractual Clauses.
What happens if you leave
The publisher commits to cease processing then return or delete data on request, with carve-outs for legal retention, backup, security, compliance and disputes.	Yes, with conditions: a perpetual license covers contact data already incorporated into your systems, but resale, redistribution, and model training remain prohibited.
Data residency and regulated cloud
Reply (ReplyApp Inc., Washington D.C., Delaware law) runs on Azure, geo-replicated across two data centers, no US region named. No SOC 2, ISO 27001, FedRAMP, StateRAMP, GovCloud, or HIPAA BAA is named, as of 2026-09-07.	Apollo hosts in the US with no region named (AWS, Google Cloud, Databricks, Snowflake, OpenAI). Own certs: ISO/IEC 27001, SOC 2 Type II (A-LIGN), CASA Tier 2. FedRAMP, StateRAMP, GovCloud, BAA absent.
What it costs
The entry price and what it includes
Multichannel listed at 89 US dollars per user per month billed annually, unlimited active contacts, unlimited emails, fifty monthly data credits, CSM onboarding.	The first paid tier, Basic, costs 49 US dollars per seat per month billed annually, with thirty thousand credits per seat per year granted upfront.
What pushes the bill up
Per-account add-ons: LinkedIn 69 US dollars monthly, calls and SMS 29 dollars monthly. Active-contact tiers and data credits add further cost.	Phone data: one email costs one credit, one phone number costs eight, and the US dialer costs two credits per call minute.
Sales tax and nexus
Reply's Terms place all taxes on the customer, excluding Reply's own income tax; withholding is likewise the customer's burden, via certificate. No tax page, no states, no local calculation as of 2026-09-07 — not a sales tool.	Apollo shifts the tax burden onto the customer (ToS §4(c)(iv)): taxes owed except those on Apollo's own net income. No tax policy page, list of states, nexus statement, or per-state/local calculation are published on 2026-09-07.
Procurement and invoicing
The only path is self-service by card, auto-renewing. Invoice billing, purchase orders, net-30, ACH, wire transfer, and a W-9 are absent as of 2026-09-07. Enterprise and AI SDR Enterprise are 'Custom' priced via booking.	Net-30 in USD (ToS), late interest 1.5%/month, subscriptions non-cancelable and nonrefundable. Major cards accepted (PayPal, Apple Pay, Google Pay excluded). ACH only for Organization/Custom plans, on request. PO and W-9 absent.

Key takeaways

Apollo builds the technical block, then disclaims the legal responsibility for it

Apollo blocks calls to numbers on the Do Not Call registry once screening is switched on — an opt-in setting, not a default — while its own contract still places TCPA and CAN-SPAM compliance onto the customer regardless. Its email opt-out link is optional, can be toggled off by the sender, and expires after forty-seven days; no SMS step exists in the product at all.

Reply.io never mentions TCPA, but does register its SMS channel

Reply.io ships an opt-out link by default on email, though the customer can remove it, and no non-compliant send is technically blocked; TCPA and calling are absent from what it publishes entirely. Its SMS channel requires A2P 10DLC registration and honors STOP requests, but the send window itself is set by the user, not enforced by the platform.

Neither company’s hosting claim carries a regulated-cloud certification

Reply, incorporated as ReplyApp Inc. under Delaware law, runs on Azure, geo-replicated across two data centers with no US region named, and publishes no SOC 2, ISO 27001, FedRAMP, StateRAMP, GovCloud, or HIPAA business associate agreement. Apollo hosts in the US without naming a region either, claiming ISO/IEC 27001, SOC 2 Type II, and CASA Tier 2 for itself, though the same four regulated-cloud items are just as absent from its pages.

Sales tax stays with the customer at both companies

Reply’s own terms place all taxes on the customer, excluding only Reply’s own income tax, with withholding likewise the customer’s burden via certificate; no tax page, state list, or local calculation is published. Apollo’s terms, at section 4(c)(iv), do the same, excepting only taxes on Apollo’s own net income, with no tax policy page or state list either.

What “compliant” means changes depending on which page you read

Apollo’s opt-in call-blocking is a real technical control, but its contract still assigns the legal duty elsewhere — a split this piece does not resolve into one verdict. Reply.io skips the calling question altogether while treating its SMS channel more strictly, with registration required and STOP honored, even though the hour at which a message goes out is left entirely to whoever configured the campaign.

Does Apollo itself block calls to numbers on the do-not-call list?

Yes, once opt-in screening is turned on: Apollo then blocks calls to numbers on the national do-not-call registry, but pushes TCPA and CAN-SPAM compliance onto the customer by contract. Its email opt-out link stays optional, toggleable off, and expires after 47 days. Reply.io has no call blocking and no TCPA mention at all. For a buyer prospecting by phone, Apollo blocks a bit more technically, but legal responsibility stays with the customer either way.

Does Reply.io offer wire transfer or purchase order as a payment option?

No: Reply.io offers only self-service card payment, auto-renewing; invoice, purchase order, net-30, ACH, wire, and W-9 are all absent. Only the Enterprise and AI SDR Enterprise tiers go through a custom quote after a sales contact. Apollo names net-30 in US dollars in its terms, with 1.5 percent monthly late interest, and opens ACH on the Organization tier by request. For a buyer who needs to process payment internally through a purchase order, neither vendor allows it through self-service.

Is Apollo’s mailbox warm-up native or provided by a third party?

Apollo’s mailbox warm-up is not native: it runs through a third party, Warmbox.ai, with one mailbox included per seat on paid plans, and 200 credits per 30-day period for each additional mailbox. At Reply.io, warm-up is included at no extra cost with every purchased mailbox, through a network of real inboxes. For a buyer running many sending mailboxes, Reply.io avoids the per-mailbox cost that Apollo charges.
