Built to run deliverability across every client you serve
You're not optimizing one sender. You're keeping a portfolio of client domains inboxed across providers, send schedules, and authentication setups. InboxAlly gives marketing agencies a multi-tenant workspace with per-client IA Score, exportable client reporting, and the engagement engine that moves reputation across every account you manage.
Built for the work agencies actually do
You're not managing one sender. You're running deliverability across a portfolio of clients, each with their own domain, ESP, send cadence, and reputation baseline. InboxAlly is built for the agencies that own that outcome end-to-end.
Per-client work doesn't scale by repeating the same audit
New client onboarding plays out the same way every time: audit authentication, check reputation, identify hygiene gaps, propose a plan. Doing that across 20 clients with hand-rolled tools means 20 spreadsheets and 20 report formats. Agency scale demands tooling that runs the workflow per-client out of the box.
Client wins are invisible without per-client data
Telling a client "deliverability improved" only lands when you can show them: which providers shifted, what their IA Score did week-over-week, where the warmup ramp landed. Generic dashboards aggregate across senders, useful for you, unusable for the client review.
When a client's reputation breaks, the bill clock starts
Clients pay you to keep email working. When a domain tanks, the question is how fast you can move it back. Manual diagnosis across SPF, DKIM, DMARC, sender history, list hygiene, and Postmaster signals burns a day per client. Agency tooling has to surface root cause across the portfolio in minutes, not days.
What InboxAlly gives agencies
A deliverability platform purpose-built for agencies running client portfolios. Per-client workspaces, per-client reporting, per-client engagement, all under one account.
Multi-tenant workspace per client
Manage every client as a separate sender profile under one account. Each profile has its own IA Score, engagement mode (warmup, repair, protect, boost), placement history, and reporting. Switching between clients takes seconds, not separate logins. Capacity scales with your plan.
See how sender profiles workPer-client inbox placement testing
Run a seed test for any client across Gmail, Google Workspace, Outlook, Hotmail, Microsoft 365, and Yahoo. Results break down by mailbox provider so you can show the client exactly which providers route their campaigns to inbox vs. promotions vs. spam, campaign by campaign. Apple Mail and additional provider coverage is available; contact support to configure your seed mix to match each client's audience.
Inbox placement testingReputation repair across every client domain
InboxAlly's core engine generates real engagement signals (opens, clicks, replies, and spam-to-inbox moves) through actual mailbox interfaces, not API calls. The reputation repair flow can reverse bad mailbox classifications (Spam to Inbox, Promotions to Primary) on each client domain. It's the mechanism that moves reputation, not just measures it.
How reputation repair worksClient reporting from the same data you operate on
Export placement results, IA Score trends, and engagement data per sender profile as CSV. Filter by client, date range, and provider. The reports your clients see come from the same data you operate against. No separate reporting layer to maintain.

Awarded for what works.
The agency deliverability toolkit
Beyond the IA Score and placement testing above, InboxAlly ships the full toolkit. What you need to manage client domains continuously, diagnose drops when they happen, and demonstrate ROI back to the clients you serve.
Audit and set up every new client domain so the work starts from a clean baseline.
Authentication audit for every new client
When you take on a client, the first audit is often authentication. DMARC Reports and Domain Analytics surface SPF/DKIM failures, alignment issues, and unauthorized sending sources across every client domain you manage, so you know what to fix before you start sending.
List hygiene audit per client
Validate any client's subscriber list against the same address-quality checks used in deliverability incident response: disposable domains, role-based addresses, spam-trap patterns, hard bounces, and syntactic errors. Surface hygiene gaps before they pull a client's inbox rate down on the next campaign.
Every client as its own sender profile
Manage multiple client domains within a single InboxAlly account, with Workspaces for the agencies that need account-level separation. Each profile runs its own engagement mode (warmup, repair, protect, boost), placement history, and reporting. Capacity scales with your plan.
Day-to-day work: testing, monitoring, and the integrations that put repair on autopilot.
Show clients exactly where their email lands
Filter inbox vs. promotions vs. spam by mailbox provider (Gmail, Outlook, Yahoo, etc.) and by client. Pinpoint which provider drove a placement change for which campaign, with date-range filtering for the client review.
Know about client problems before clients do
InboxAlly monitors each connected client's Postmaster data continuously and surfaces alerts when Gmail reputation signals shift (domain reputation changes, spam rate movement, delivery errors), so you find out about a client problem before the client does.
Spot the drifting client before they notice
Side-by-side view across your client book: IA Score, placement, engagement, and reputation trends all visible at once. Available via the Reports module with multi-select sender profiles.
CRM integrations + REST API
Native CRM integrations with HubSpot, Klaviyo, and more let you wire client ESPs in directly, and Adaptive Autowarmup pairs with those integrations so warmup runs without daily intervention. For anything custom, the REST API covers seeds, sender profiles (including bulk engagement-preset changes by domain or tag), and broadcasts.
Per-client reporting and trend data. The artifacts that make the case for the agency at every review.
QBR-ready client reporting
Export placement and reputation data per client as CSV, filterable by date range and provider. Build the QBR deck from the same data you operate on. No separate reporting layer required.
Domain Reports per client
Ongoing visibility into authentication status (SPF, DKIM, DMARC compliance), Postmaster trends, and domain health signals per sending domain, consolidated in one place per client.
The chart you put in the client review
Trend lines for IA Score and inbox placement per client over time, across warmup phases, repair campaigns, and live sending periods. The progression chart that makes the case for the agency retainer at the next renewal.
Questions email marketing agencies ask
Can I manage multiple client accounts in one workspace?
Yes. InboxAlly supports multiple sender profiles under one account, with per-profile IA Score, engagement modes, and reporting. Agencies typically use this to centralize client work: either managing all client sender profiles within one account, or administering separate client accounts with shared access. Plan tier determines how many sender profiles you can run simultaneously (ranging from 1 on Starter to unlimited on Enterprise).
Can I export reports to share with clients?
Yes. Export placement results, IA Score trends, and engagement data per sender profile as CSV. Filter by client, date range, and provider. The reports your clients see come from the same data you operate against, so there's no separate reporting layer to maintain or sync.
How does InboxAlly compare to other deliverability tools for agencies?
InboxAlly is a deliverability platform with four core capabilities: per-provider IA Score tracking, inbox placement testing, Google Postmaster integration, and engagement-driven reputation repair, all multi-tenant under one account. Its engagement engine uses real mailboxes operated through actual browser interfaces, producing genuine behavioral signals. The same engine supports the full sender lifecycle: new-domain warmup, ongoing protection, and reputation repair on degraded senders, across every client you serve. See the comparison pages for how InboxAlly stacks against specific alternatives.
How fast can a client see results?
Real-world example: Dara Sklar, an email marketing specialist, used InboxAlly to increase her clients' open rates from 6–10% to 30% (roughly 3x) and reduce spam rates from 50% to as low as 2%, with measurable improvements visible across multiple client industries within a 10-day structured warm-up. Timelines depend on each client's starting reputation and the volume of seed engagement relative to live sends. The engagement engine begins generating positive signals immediately on the first send. Provider scoring systems lag the underlying behavioral change by days to weeks, so the visible score moves after the actual reputation does, which is normal.
Do I need to be a deliverability expert to use InboxAlly?
No. The IA Assistant is an in-app AI grounded in your account data and trained on InboxAlly's deliverability playbook, so you can ask why a client's IA Score shifted and get an answer based on real data rather than generic advice. Every plan also includes a dedicated Customer Success Manager plus access to our deliverability team via email, live chat, phone, and Zoom. Agencies that aren't deliverability shops can run InboxAlly without hiring a specialist.
What's included in support? Do agencies get a dedicated team?
Every InboxAlly plan ships with a dedicated Customer Success Manager plus access to our deliverability team. Support channels include email, live chat, phone, and Zoom. CSMs work with agencies on client onboarding, repair strategy for degraded sender domains, and ongoing optimization across the client book. Higher tiers add deeper involvement and faster response. The IA Assistant is available in-app on every plan as a first stop for account-grounded questions.
Is there an Enterprise tier for large agencies?
Yes. InboxAlly's Enterprise tier is built for agencies running large client portfolios, with capacity for unlimited sender profiles, expanded reporting, deeper integration support, and a more involved engagement model with our deliverability team. The Enterprise scope is best had as a conversation: book a demo and we'll scope the right plan against your client book.
Is there an API or programmatic access?
Yes. InboxAlly exposes a REST API covering three resource areas: seeds (list, shuffle, manage), sender profiles (create, update, bulk-change engagement presets by domain or tag), and broadcasts (placement results filtered by provider or sender). Common agency use cases: pulling per-client placement data into a custom dashboard, automating engagement mode changes when a client's inbox rate drops, and programmatically syncing seed lists to a client's ESP.
How granular is the per-client reporting?
Placement results break down by mailbox provider (Gmail, Google Workspace, Outlook, Hotmail, Microsoft 365, Yahoo) and by sender profile (client), with date-range filtering and period-over-period comparison. Domain Reports surface authentication compliance (SPF, DKIM, DMARC), Postmaster-sourced reputation signals, and trend data per client domain. Data is exportable as CSV with configurable column selection.
What is the IA Score?
IA Score is InboxAlly's proprietary sender-reputation index, scored 0–100%, representing your predicted inbox placement rate. It's built from your seed email placement history, weighted toward recent performance, and updated daily. The score breaks down per mailbox provider, so when it moves you can see which provider drove the change. Score ranges: 95–100% Excellent, 85–94% Good, 70–84% Fair, below 70% Needs Attention.
