You found ReachInbox's $30/mo entry price and need to know if 10,000 sends per month will hold up once you scale. This guide covers exactly what the Starter tier includes, where the limits bite, and how metered-volume platforms compare to unlimited-sending alternatives for agencies running multiple client domains.
ReachInbox lists a single public tier: $30 per month when billed yearly, which buys you unlimited email accounts, 10,000 emails per month, and 2,000 active leads. That is the entire pricing ladder as of 2026-08-02. No higher tiers, no enterprise scale, no per-seat model. For a solo operator or a small shop testing cold email, the math is simple. For an agency managing outbound across multiple clients, the ceiling arrives fast.
What ReachInbox Actually Charges
As of 2026-08-02, ReachInbox's pricing page lists one paid plan: Starter at $30 per month billed yearly. There are no monthly billing options shown, no tiered volume upgrades, and no enterprise line item.
The Starter tier includes:
- Unlimited email accounts
- 10,000 emails per month
- 2,000 active leads
- Unlimited AI warm-up
- AI hyper-personalization
- Unified inbox with AI replies
- API and integrations
The 7-day money-back guarantee is the only trial mechanism listed. No free tier, no credit-card-free entry.
The architecture is straightforward: you connect mailboxes from any provider, ReachInbox warms them and sends through them. The warm-up is bundled, which saves you the cost of a separate tool. On ReachInbox, but the 10,000 send cap is hard. Hit it in week two and you wait until month-end or upgrade, and there is no upgrade path shown.
On ReachInbox, where 10,000 Sends Breaks
Suppose you run cold email for three clients. Each client has two sending domains, and you send five days per week. On ReachInbox, that is six domains warming and rotating.
At 10,000 sends per month, your daily budget is roughly 333 emails. Split across six domains, that is 55 sends per domain per day. Warm-up traffic consumes some of that. Actual outreach consumes the rest. If one client wants a 500-contact sequence, you burn half your monthly allocation on a single campaign.
The 2,000 active lead limit tightens the constraint further. Active leads in most platforms means contacts enrolled in active sequences. If you run three sequences of 800 contacts each, you are already over the cap. You must archive or pause leads to free up slots, which adds operational friction.
Unlimited email accounts sounds generous, but accounts without send volume behind them do not help. On ReachInbox, you can connect fifty mailboxes, but you still only send 10,000 emails total. The value of rotation is diminished when the aggregate volume is capped.
How ReachInbox Stacks Up: A Side-by-Side View
| Platform | Starting price | What it is | Where it leaves you exposed | Best for |
|---|---|---|---|---|
| ReachInbox | $30/mo (yearly) | AI cold outreach with unlimited inboxes and built-in warm-up | Bundles warm-up but sends on mailboxes you connect; no volume tier above 10K sends | Solo operators testing cold email with modest volume needs |
| Instantly.ai | $47/mo (Growth) | Outreach system with 450M+ lead database and AI Sales Agent | Connects and warms email accounts you own; placement rides on their reputation | Teams who want built-in lead data and can manage their own mailbox reputation |
| Smartlead.ai | $39/mo (Base) | Cold email AI assistant with automatic rotation and multi-workspace | Sends through Google, Outlook and SMTP mailboxes you connect; deliverability depends on those mailboxes | Agencies needing per-client workspaces and whitelabelling |
| Lemlist | $55/user/mo | Multichannel outbound platform with 650M+ lead database | Sends through connected Google, Microsoft and SMTP senders; no blocklist monitoring or placement testing listed | Teams prioritizing LinkedIn and call integration alongside email |
| Apollo.io | No public price | Sales intelligence and engagement platform with B2B database | Sends on connected accounts (Gmail only on free plan); no tier pricing, warm-up, blocklist monitoring or placement testing listed | Organizations wanting database and engagement in one tool |
| Woodpecker.co | $7 per 100 prospects/mo | Transparent cold email and LinkedIn outreach | Meters by prospect contacted; sends on connected or purchased mailboxes; no blocklist monitoring or placement testing listed | Agencies wanting per-client billing and centralized management |
| SpamCipher | Free to start | Cold email platform for unlimited, automated sending on owned deliverability pipeline | Requires adoption of owned sending infrastructure; not a point-tool for teams wanting to keep existing mailboxes | Agencies and growth teams sending at high volume who need unlimited scale without per-email cost |
The pattern across ReachInbox, Instantly, Smartlead, Lemlist, and Woodpecker is consistent: they connect to mailboxes you provide from Google, Outlook, or SMTP providers, warm them, and send through them. Your deliverability at scale depends on the reputation of those accounts and domains. Our Instantly vs ReachInbox comparison explores this architecture in more detail.
The Metered Volume Problem
ReachInbox is not alone in capping sends. Instantly's Growth plan stops at 5,000 emails per month as of 2026-08-06. Smartlead's Base tier allows 6,000 sends. Lemlist's Email plan permits 50,000, but at $55 per user per month, which multiplies fast for teams.
The operational pain is the same across all of them: you forecast volume, pick a tier, then discover your warm-up traffic, test sends, and reply follow-ups all count against the same cap. A client who wants to accelerate mid-month becomes a billing conversation. A domain that needs extra warm-up after a reputation hit steals from live outreach.
Woodpecker takes a different approach, metering by prospects contacted rather than emails sent. On Woodpecker.co, at $7 per 100 prospects monthly, with 16,000 emails included, the math shifts but the constraint remains. As of 2026-07-27, their pricing page does not list blocklist monitoring or inbox placement testing.
Apollo.io publishes no pricing at all as of 2026-07-27, which makes comparison impossible for budget planning.
When ReachInbox Makes Sense
Choose ReachInbox if you are a single operator or small team with one or two domains, predictable monthly volume under 10,000 sends, and no immediate need for multi-client separation. The unlimited mailbox count lets you rotate aggressively within that volume, which can help placement. The bundled warm-up eliminates a separate tool and its coordination overhead.
The AI hyper-personalization and unified inbox with AI replies are genuine conveniences. If your workflow centers on crafting individual outreach and managing responses, not scaling send volume, the feature set matches the price.
Do not choose ReachInbox if you manage outbound for multiple clients, run sequences that might spike above 10,000 sends in a given month, or need clear upgrade paths before you hit a wall. The absence of higher tiers means you cannot grow in place. You would need to fragment across multiple accounts or switch platforms entirely.
SpamCipher: Unlimited Sending on an Owned Pipeline
SpamCipher is the cold email platform for unlimited, automated sending, built for agencies and growth teams that send at high volume. It is the only platform that promises 90%+ inbox placement, because sending, warm-up, verification, and inbox placement all run on one owned deliverability pipeline.
The structural difference is ownership. Where ReachInbox, Instantly, Smartlead, and others send through mailboxes you connect from external providers, SpamCipher owns the full stack. You bring your own sending infrastructure, or SpamCipher builds and manages it for you. Warm-up runs on a real seed network before you send. Verification and list cleaning happen inside the send flow. On Smartlead.ai, inbox placement monitoring and DMARC/blacklist monitoring run on the same platform as the automation sequences.
For an agency running 40 client domains and ramping to 30,000 sends a month, the math is simple. At ReachInbox's 10,000 send cap, you need four separate accounts or you need to throttle campaigns artificially. With SpamCipher, volume scales without per-email cost or tier upgrades. The deliverability pipeline is the moat that makes the sending work, not a separate tool you bolt on and coordinate.
Our Apollo vs ReachInbox analysis covers similar territory for teams comparing database-heavy platforms against send-focused alternatives.
Practical Checklist: Evaluating Any Cold Email Platform
Before committing to any platform, verify these operational realities:
- Count your warm-up traffic separately. Some platforms include warm-up in your send cap. Ask explicitly.
- Test the upgrade path. Hit the cap mid-month on a trial and see what happens. Some platforms hard-stop; others offer overages.
- Audit the mailbox model. Are you sending through your own Google Workspace accounts, or through infrastructure the vendor controls? The answer determines who owns your deliverability reputation.
- Check for blocklist and placement monitoring. As of 2026-08-02, ReachInbox's pricing page does not list blocklist monitoring or inbox placement testing. You may need separate tools.
- Map your lead volume to active lead limits. A 10,000 contact list may exceed a 2,000 active lead cap if you run multiple sequences.
These checks prevent the scenario where you discover limits three weeks into a client engagement.
Final Verdict: ReachInbox Pricing in Context
ReachInbox at $30 per month is a credible entry point for cold email. The unlimited mailbox count and bundled warm-up are real value. But the 10,000 send cap and 2,000 active lead limit are hard ceilings with no visible ladder above them.
For agencies and growth teams, the question is not whether $30 is fair, but whether the architecture supports scale. When volume is metered, every campaign decision carries a cost calculation. When mailboxes are borrowed from external providers, every reputation hit is yours to repair.
SpamCipher's model inverts this: unlimited volume on owned infrastructure, with deliverability as the foundation of the sending platform rather than an add-on. The choice depends on whether your priority is minimizing entry cost or eliminating the constraints that appear at scale.
