Quotarider

Cold email + CRM + attribution · quotarider.com

Best for: Teams sending from a domain they can't afford to lose, who want the CRM and revenue reporting in the same tool.

Cold email sequences from your own mailboxes behind a per-send risk score (the Sequence Guardrail), a CRM that fills itself from replies, and attribution to the paid invoice — in one database.

Strengths
  • A 100-point risk score on every send that can pause a sequence — no cap setting overrides it
  • Full CRM included: replies become deals, meetings attach themselves
  • Attribution follows each deal to the paid invoice
  • Flat plans from $49 a month with mailboxes included; free plan
Watch-outs
  • No built-in contact database — import from Apollo, Clay or CSV
  • No warm-up network, by design: new mailboxes ramp with real, capped sends
  • LinkedIn steps are manual tasks, not automated

Pricing model: Free plan; Starter $49, Team $199, Growth $599 a month. See plans →

Instantly

Cold email sequencer · instantly.ai

Best for: You run many disposable domains, measure success in meetings booked per month, and need the largest possible send volume for the lowest possible price.

Instantly is a cold email sending platform built for volume: unlimited connected email accounts on paid plans, a large shared warm-up network, a unified inbox, a B2B lead database sold separately, and a light deal pipeline added in 2024–25. Pricing is tiered by active contacts and monthly sends.

Strengths
  • Connect as many mailboxes as you like and rotate across all of them
  • Warm-up runs automatically through a large peer network
  • A big built-in lead database (paid separately) for finding contacts
  • Straightforward for agencies running dozens of client domains at high volume
Watch-outs
  • Warm-up traffic is synthetic conversations sent from your domain to strangers' inboxes — Google has said it treats such patterns as a signal
  • There is no per-send risk score; a bad list or a young domain can burn through the daily cap before anything stops it
  • The pipeline is a lightweight add-on, not a CRM: no multi-threaded deals, no quotes, no invoice attribution

Pricing model: Instantly is priced by active contacts and monthly email volume, with the lead database and CRM tier as separate subscriptions. Quotarider is a flat monthly plan that includes users, mailboxes, contacts and sends together, from a free plan up to enterprise; AI runs on your own key with no markup. Quotarider vs Instantly →

Smartlead

Cold email platform for agencies · smartlead.ai

Best for: You are a lead-gen agency selling volume, your clients measure you in meetings booked, and you already have a reporting stack for everything after the reply.

Smartlead is a cold email platform aimed at lead-generation agencies: unlimited mailboxes and warm-ups, a master inbox across clients, client sub-accounts, white-label options and an API. It is priced by active leads and monthly email volume.

Strengths
  • Unlimited mailboxes and warm-up on every paid tier
  • Agency features that matter: client sub-accounts, white label, master inbox
  • Solid API and webhooks for agencies with their own tooling
  • Popular and well documented for high-volume outbound
Watch-outs
  • Volume is the product; there is no risk score that can hold a sequence when a client's domain starts to degrade
  • Warm-up depends on a shared network of other customers' mailboxes
  • No CRM: deals, quotes and revenue live in the client's own tools, so agency reports stop at replies and meetings

Pricing model: Smartlead is priced by active leads and email volume per tier. Quotarider is a flat plan per workspace that includes mailboxes; agencies run several client workspaces from one login and earn partner commission on the subscriptions they bring. Quotarider vs Smartlead →

lemlist

Multichannel outreach platform · lemlist.com

Best for: Image and video personalisation and automated LinkedIn steps are the core of your motion, and you are happy paying per seat plus credits.

lemlist is a multichannel sales engagement tool known for personalisation — custom images, dynamic landing pages, video — plus LinkedIn automation steps, a warm-up product (lemwarm) and a B2B lead database. It is priced per user, with data credits on top.

Strengths
  • Best-in-class personalisation: images, landing pages, liquid syntax, video
  • LinkedIn steps (visits, invites, messages) automated inside the sequence
  • A lead database and enrichment inside the product
  • A large template library and an active community
Watch-outs
  • Per-seat pricing gets expensive for a team, and enrichment credits are metered on top
  • Warm-up (lemwarm) is a separate product built on the same shared-network idea
  • The CRM is light; deals and revenue usually live in HubSpot or Pipedrive via integration

Pricing model: lemlist is priced per user with tiered features and enrichment credits. Quotarider is a flat monthly plan that includes users and mailboxes, with a free forever tier and AI running on your own provider key at no markup. Quotarider vs lemlist →

5

Apollo

B2B database with sequences · apollo.io

Best for: Finding contacts is your bottleneck, volume is modest, and your CRM of record is Salesforce or HubSpot.

Apollo.io is a B2B contact and company database first — hundreds of millions of records with export credits for emails and phone numbers — with sequences, a dialer, meetings and a light CRM built around it. It is priced per user with credit limits per tier and a generous free plan.

Strengths
  • A huge contact database with filters, intent signals and a Chrome extension
  • Sequences, dialer and meeting scheduling in one place
  • A free plan that is actually usable for prospecting
  • Widely used as the data source next to another CRM
Watch-outs
  • Sending from Apollo puts high volume through your mailboxes with basic deliverability controls and no per-send risk score
  • The CRM is designed to feed Salesforce or HubSpot, not to replace them
  • Credits meter the thing you came for — emails and phone numbers

Pricing model: Apollo is priced per user with monthly credits for emails and phone numbers. Quotarider is a flat plan including users and mailboxes; there are no data credits because Quotarider does not sell data. Quotarider vs Apollo →

Reply.io

Multichannel sales engagement · reply.io

Best for: You need LinkedIn and messaging steps in the same sequence builder today and already run a separate CRM you are happy with.

Reply.io is a multichannel sales engagement platform: email sequences with LinkedIn, call and messaging steps, an AI SDR assistant, a contact data add-on, email warm-up, and pricing by users or mailboxes depending on the plan.

Strengths
  • Broad multichannel sequences in one builder
  • AI assistant for writing and replying
  • Built-in contact data option
  • Agency-friendly plans
Watch-outs
  • No per-send risk score that can hold a sequence when a mailbox or domain starts to degrade
  • Warm-up relies on a network of other senders' mailboxes
  • CRM is integrations-first; deals, quotes and invoices live elsewhere

Pricing model: Reply.io is priced per user or per mailbox by plan, with data and AI features as options. Quotarider is a flat plan including users, mailboxes and sends, with AI on your own key and plans from $49 a month. Quotarider vs Reply.io →

Woodpecker

Cold email tool · woodpecker.co

Best for: You want a focused, simple cold email tool and already have a CRM you like.

Woodpecker is a cold email tool known for its focus on deliverability and simplicity: sequences with conditions, bounce protection, warm-up and recovery options, an agency panel, and pricing based on the number of prospects you contact.

Strengths
  • Deliverability-minded defaults and bounce protection
  • Simple sequence builder with conditions
  • Agency panel for client accounts
  • Clear pricing model
Watch-outs
  • Protection is mostly rules and limits rather than a per-send score across reputation, pressure and timing
  • Warm-up relies on a network of mailboxes
  • No built-in CRM; deals and revenue live in another tool

Pricing model: Woodpecker is priced by contacted prospects and options such as warm-up. Quotarider is a flat plan including users, mailboxes and sends, from $49 a month. Quotarider vs Woodpecker →

How to choose

Four questions that decide it.

Where does it send from?

Your own mailboxes on your real domain, or a pool of separate sending domains? It decides how much a mistake costs.

What stops a bad send?

Daily caps and warm-up, or a per-send check that can hold a sequence when bounces or complaints rise?

Where do replies go?

A unified inbox, a sync to your CRM, or a CRM in the same database — which decides whether attribution survives.

How is it priced?

Per seat, per contact, per mailbox or flat — and what's billed on top (data credits, AI, warm-up).

Questions, answered

Is cold email still effective in 2026?

Yes, when it is relevant, low-volume per mailbox and sent from authenticated domains. Google and Yahoo's bulk-sender rules (complaints under 0.3%, one-click unsubscribe) punish volume without relevance.

Is cold emailing illegal?

Not in most places for B2B, with conditions: the US (CAN-SPAM) is opt-out; the UK allows email to corporate subscribers with an opt-out; Canada (CASL), Germany and the Netherlands generally need consent. See our country pages — summaries, not legal advice.

What is the best free cold email software?

Quotarider has a free plan with one user, one mailbox and the CRM. Several others offer trials rather than free plans.

Do I need email warm-up?

You need a gradual ramp. Warm-up networks that trade synthetic replies are one way; Quotarider ramps with real, capped sends instead.

Try the one with the brake pedal.

Free plan, one mailbox, no card. The guardrail is on from the first send.
