Google WorkspaceMicrosoft 365LinkedInWhat is SignoFast?
SignoFast offers two independent products: Email Outreach for email campaigns and LinkedIn Outreach for LinkedIn campaigns. Buy both to run multichannel sequences and reply from one Unibox.
Agencies running client campaigns, B2B SaaS founders doing their own outbound, and sales teams consolidating email and LinkedIn tools.
Pricing: Email Outreach: $39/month billed monthly, or $384/year billed annually ($32/month equivalent; save 18%) per workspace. LinkedIn Outreach: $30/month per account billed monthly, or $288/year per account billed annually ($24/month equivalent; save 20%). See full pricing.
SignoFast brings email and LinkedIn outreach into one workflow builder, with standalone products for each channel and clear pricing for teams that use both.
Most tools claim unlimited mailboxes and warmups. What they often hide: fixed lead pools, monthly send ceilings, restricted warmup, and Unibox reply paywalls. SignoFast offers Email Outreach and LinkedIn Outreach as separate products that teams can combine for multichannel workflows. See our guides on Instantly alternatives, email warmup, and Unibox.
Instantly Growth caps uploaded contacts at 1,000 total. SmartLead Base holds 2,000 active leads. These are fixed lifetime pools, not monthly resets. Past 1k contacts you are forced to pay $97 per month.
Starter tiers automatically cut you off and pause campaigns around 5,000 to 6,000 emails per month. Scaling sends means jumping to high-tier plans before you even add a single teammate.
Competitors lock direct two-way Unibox replies behind higher tiers or demand a separate CRM fee just to reply to interested leads. Without it, teams must log in to many mailboxes manually.
There's a better way.
Features
Run email campaigns with multi-step sequences, or multichannel campaigns that mix email and LinkedIn. Email Outreach includes email warmup; each workspace needs the matching product for every channel used. LinkedIn outreach depth and team workspace features follow below. See pricing.
Google, Microsoft, and SMTP
Email warmup gradually ramps send volume and engagement on each connected mailbox so new or cold accounts build sender reputation before full campaign volume. SignoFast runs this automatically, with no separate warmup tool.

LinkedIn channel
Run LinkedIn as its own outreach product or combine it with Email Outreach in multichannel sequences. Connect account-level seats, use conditional paths and campaign actions, and manage replies in Unibox.
LinkedIn Outreach is available on its own at $30/month or $288/year per account. See LinkedIn Outreach pricing.
Included with LinkedIn outreach
Each LinkedIn account can run on a dedicated IP matched to a country. A custom IP option is available when you need more control.
LinkedIn messages and InMail sit beside email replies in one Unibox. Filter by account, campaign, or unread, then reply without leaving SignoFast.
Build outreach like a flowchart. After each step, choose what happens next based on real outcomes: accepted, not accepted, replied, or no reply. See the full path at a glance.
Use every supported LinkedIn action in a sequence, alone or chained with email. Attach conditions so the next step only runs when the lead behaves as expected.
One seat covers one connected LinkedIn account. Each lead stays on the same account for the full sequence so conversations stay consistent.
Campaign builder
Every campaign starts with a clear choice. Stay on email, or combine channels so you control exactly what happens after each step. Email workflows require Email Outreach, LinkedIn workflows require LinkedIn Outreach, and workflows using both need both products.
Linear sequences with warmup, variants, tracking toggles, and timezone-aware scheduling. Ideal when you only need email.
Build your sequence like a flowchart. Drag, drop, and branch email and LinkedIn actions. See the full outreach path at a glance.

Answers about products, billing, LinkedIn seats, workflows, and replies.
SignoFast offers two independent products: Email Outreach and LinkedIn Outreach. Each can be purchased on its own. Choose both to build campaigns that combine email and LinkedIn steps in one workflow.
Email outreach software helps you send personalized messages to prospects at scale while managing deliverability, follow-ups, and replies. SignoFast connects your real accounts (Google, Microsoft, or SMTP), warms them up, runs campaigns with sequences and variants, tracks performance, and routes every reply into one Unibox.
SignoFast protects sender reputation at every step: automated warmup on every account, smart pacing and inbox rotation, proper random delays between sends, timezone-aware send windows, and bounce and reply handling built in. For LinkedIn, plan-aware daily limits keep accounts within safe bounds. The platform is built around the practices that keep mailboxes healthy and outreach sustainable as you scale.

Yes. SignoFast supports Microsoft 365 and Outlook mailboxes via Microsoft OAuth, with email account rotation, warmup, sequences, Unibox, and analytics.
Yes. Any provider that supports SMTP/IMAP can be connected alongside Google and Microsoft accounts, so agencies and teams are not locked into one vendor.
Google and Microsoft OAuth connect your Workspace or Microsoft 365 identity with provider-native auth. SMTP/IMAP connects any compatible mailbox (including custom domains on other hosts). SignoFast supports both so you can mix providers in one workspace.
Email warmup gradually increases sending volume and engagement signals so new or cold accounts build sender reputation before full campaign volume. SignoFast automates warmup for every connected account so deliverability stays healthier as you scale.
Email Outreach supports unlimited connected email accounts, with no per-mailbox fee.
Upload or sync the audiences you want to contact. SignoFast focuses on delivery, pacing, rotation, analytics, sequences, and replies so your lists run through one outreach workflow.
A workspace is an isolated environment for campaigns, leads, connected accounts, and analytics. Data stays separate between workspaces. Product subscriptions are selected for the channels used in each workspace.
Owner has full access. Admin can do everything except billing and ownership transfer. Editor manages campaigns. View/VA can monitor the workspace, manage sending accounts, and reply in Unibox.
Unibox brings replies from connected email accounts into one place. LinkedIn conversations also appear there when your workspace has LinkedIn Outreach, so your team can review and respond across the channels it purchased.
Email Outreach includes unlimited email accounts, active leads, warmup, and emails subject to fair use. LinkedIn Outreach is a separate product billed per connected account. Buy both to use email and LinkedIn in one multichannel workflow.
SignoFast can fit teams looking for email outreach at a per-workspace price, LinkedIn outreach priced per connected account, or both in one workflow builder. Email Outreach is $39/month billed monthly or $384/year billed annually per workspace. LinkedIn Outreach is $30/month billed monthly or $288/year billed annually per LinkedIn account.

Yes. Export your lead lists from your current tool and import them into SignoFast, then reconnect Google, Microsoft, SMTP, and LinkedIn accounts. Rebuild sequences in SignoFast’s email or multichannel builder to match your existing flows.
You own your leads, campaign content, and connected-account outreach data. SignoFast processes it to provide the Service. See the Privacy Policy for retention, processors, and your rights under GDPR and CCPA where applicable.
Yes. For example, a campaign can send a LinkedIn connection request, wait for acceptance, then send a LinkedIn message or an email follow-up. Email steps require Email Outreach, LinkedIn steps require LinkedIn Outreach, and a workflow using both channels requires both products.
SignoFast detects your LinkedIn plan tier and recommends daily limits based on that tier and account health, with extra caution for new or smaller accounts. You can edit daily caps per action, weekly invite and message limits, and monthly personalized invite-note quotas. Sending respects timezone, day-of-week, and time windows. If a session drops, the account is marked reconnect required and stops receiving new outreach until you reconnect.
LinkedIn Outreach is $30/month per account, or $288/year per account billed annually ($24/month equivalent). Save 20%. One purchased LinkedIn seat allows one connected LinkedIn account.
Yes. LinkedIn Outreach is an independent product at $30 per month per connected LinkedIn account, or $288 per account per year when billed annually. Email Outreach is only needed if your campaigns also include email steps.
One purchased seat covers one connected LinkedIn account. Seats are counted per LinkedIn account, not per teammate, so multiple teammates can work in the same workspace without each needing a seat.
Pricing scales with the number of connected LinkedIn accounts. For example, three accounts cost $90 per month billed monthly, or $864 per year billed annually ($72 per month equivalent). Each purchased seat covers one connected account.
Email Outreach plus one LinkedIn account costs $69 per month billed monthly, or $672 per year billed annually ($56 per month equivalent). Each additional LinkedIn account adds $30 per month or $288 per year.
LinkedIn campaigns support connection requests, messages, InMail, profile visits, post reactions, comments, follows, and pending invite withdrawals. Build condition-based workflows that branch on connection acceptance, replies, or no reply, add wait times, and stop outreach when a lead replies.
Yes. LinkedIn messages and InMail appear in Unibox, where you can review and reply to conversations. Email replies also appear there when your workspace has Email Outreach.
LinkedIn Outreach includes unlimited campaigns and active leads. LinkedIn actions still follow account-level daily and weekly limits, which you can configure to match your account and activity needs.
