Best cold email agencies for small B2B companies (2026)
This list ranks eleven cold email agencies by the lowest monthly amount a small company can start at, using the entry price each agency publishes on its own site; agencies that publish no price follow, month-to-month ones first. Prices read 28 October 2026. Sales.co is our own service, so weigh its position with that in mind.
Seven of the eleven publish a figure. Sales.co starts lowest at $2,000 a month for up to 10,000 emails, then OutreachBloom at $2,400 and CIENCE at $4,249 a month with one offshore SDR. Belkins and LevelUp Leads start from $5,000, Hypergen from $6,500 and Callbox estimates $6,667 a month for one pod.

OutreachBloom lists cold email outreach at "starts at $2,400/mo" for 10,000 to 100,000 targeted B2B contacts a month. It builds the infrastructure and the lead list, writes the messaging for your approval, runs A/B tests and manages replies.

3. CIENCE
CIENCE prices in three parts: a campaign team at $2,000 a month, its graph8 platform at $499 a month with 75,000 credits, and SDRs from $1,750 a month each offshore or $3,500 in the US or Europe. One offshore SDR makes $4,249 a month before a performance bonus and a one-time setup fee whose amount the page does not give. CIENCE states month to month terms with no long contract and a launch in under 14 days. Its own worked example, five offshore SDRs, comes to $11,249 a month plus bonus.

4. Belkins
Belkins gives "the average starter price: from $5,000" with 1,500 leads a month and 100+ guaranteed appointments a year. The page does not say whether the $5,000 is monthly, and it states no contract term. Anything above the starter scope is a custom proposal based on company size, market and goals. Belkins is the only agency on this list that guarantees a meeting count on its own pricing. Source: belkins.io/cold-email-services · Sales.co vs Belkins.
5. LevelUp Leads
LevelUp Leads states pricing "starting at $5,000" across three tiers: Fractional SDR, Full-Service SDR and Growth. Its Growth tier lists 700+ calls and 460+ emails a business day and 3,000 to 4,000+ contacts sourced a month. Payment is prepaid monthly, with an initial 3-month commitment before it rolls to month-to-month. A small company therefore commits $15,000 before it can stop. Source: levelupleads.io/pricing.
6. Hypergen
Hypergen's Lite plan is "from $6,500/mo" with a 6-month minimum agreement and 7,500 prospects contacted a month. Lite includes direct CRM integration and reporting for Hypergen leads.

8. Cleverly
Cleverly publishes no price; its pricing section says "Month-to-month, no contracts. Book a call to learn more." It offers two plans: Growth, a flat monthly retainer, and Scale, priced per lead. Both list unlimited campaigns, "thousands of emails monthly", list building and domain setup. Source: cleverly.co/cold-email-outreach-agency · Sales.co vs Cleverly.
9. Leadium
Leadium publishes no price, and its pricing page is a consultation form. The form's budget field starts at "$2,500 to $3,500" and runs to "Above $10,000", which shows the range it quotes in.

11. Martal Group
Martal Group publishes no price; its pricing page says "Inquire about pricing" for every plan. Each plan starts with a pilot campaign, 3 months with an onshore team or 4 months with a fractional team, then moves to a monthly subscription. Some plans add a sales commission to the flat monthly fee. A small company commits to at least three months before it learns whether the channel works.

How this list was made
We kept agencies that run cold email as a managed service and that buyers name for small B2B companies, then read each one's own pricing page on 28 October 2026. Martal Group blocks automated readers, so its page was read in a browser. "Not stated" and "Not published" mean the agency's site gives no figure; we did not use third-party estimates.
Entry price is the smallest monthly amount the agency publishes. CIENCE's figure adds its two fixed fees to one offshore SDR. Belkins does not give a billing period, so its $5,000 is treated as one month.
