A cold email agency service for B2B teams: we build the list, write the emails, send them and handle the replies.

What this cold email agency service is

Jeluvi's cold email agency service is B2B cold outreach by email, done for you. Jeluvi, owned and run by Marko Ristić, builds the list from your customer profile, researches the people on it, writes the emails, sends them with follow-ups, answers the replies and hands qualified conversations to your sales team.

In B2B lead generation, cold email is one outbound channel among several. A cold email agency takes over the daily work of the campaigns: lists, copy, sending, deliverability and replies. Your sales team keeps the conversations that qualify, and the leads that turn into deals.

It is one of three services Jeluvi sells, each done for the client: LinkedIn outreach, cold email and B2B lead generation. This page covers email only. The other two are described further down, where the channels are compared.

Jeluvi is new. There are no clients, case studies or results to show yet, and this page does not pretend otherwise. What you can check instead is the method: every step of the work below links to the guide on this site that explains how that step is done.

Who this is for, and who it is not for

Cold email outreach works when the right message reaches the right person at a company that can buy. It does not repair an offer nobody wants. Read both lists before you fill in the form; a bad fit costs you money and costs the sending domain its reputation.

A good fit

• You sell to businesses. Your buyers have work email addresses at company domains, and a single sale is worth a real conversation with a decision-maker.
• You know who buys. You can name customers who bought, and why, even if the profile is not written down yet.
• The offer already closes. Meetings with the right people turn into deals today, and you want more of those meetings.
• Nobody has the hours. You or your reps can take meetings, but cannot also research, write and send every working day.
• You want to see the work. You would rather approve the emails and read the replies than receive a monthly total.

Not a good fit

• No customers yet. Cold email can test a market, but it cannot tell you why nobody buys. Talk to buyers first.
• Consumer audiences. This service writes to people at companies about their work, not to personal inboxes about their private lives.
• Volume above all. If the goal is the largest possible number of sends, a bulk email platform fits better than a researched campaign.
• A guaranteed number. Jeluvi does not promise meetings, replies or revenue, because nobody can honestly promise them before a single email has gone out.
• A bought list, mailed as it is. Google tells senders not to purchase email addresses, and Yahoo tells senders not to purchase mailing lists. A file you bought is not a campaign this service will send.

What is included: the cold email outreach work, step by step

This is the work as Jeluvi runs it, in order, from the customer profile to the meeting on your calendar. Each step links to the guide on this site that explains the method in depth, because the service runs on the same methods those pages describe.

1. Customer profile and offer

   The work starts from your ideal customer profile: industries, company size, regions, the roles that buy and the problem they pay to solve. If it is not written down, it gets written with you from the customers you already have, before a single address is found.

2. List building

   The list is built for your campaign from that profile: target accounts first, then the decision-makers in the roles that matter. How a list like this is made is laid out in how to make a prospect list. Which data sources are used is agreed on the first call.

3. Verification and list hygiene

   Every address is checked before it is used, risky ones such as catch-all domains are handled separately, and anyone on your exclusion list is removed. The rules behind this are in the email hygiene entry.

4. Research and personalization

   Each account gets a short note on why it fits and what is happening there now: hiring, a launch, a new leader. The method is in company research for sales. That note sets the angle of the first email, so the outreach is signal-based, not a merge field.

5. Copywriting

   Emails are short and plain, written to one role about one problem, ending in a question that is easy to answer. The approach follows how to write a cold email. You approve the first email and every follow-up before anything is sent in your name.

6. Sending setup and deliverability

   Sending domains and mailboxes are authenticated with SPF, DKIM and DMARC and warmed up before campaign volume, as described in email deliverability and email warm up. Whose domains and mailboxes are used is agreed on the first call.

7. Sending and follow-up

   Emails go out at a steady daily volume, with follow-ups spaced days apart and stopped the moment someone replies or opts out. How those follow-ups are written is covered in follow up email after no response.

8. Reply handling

   Every reply is read and sorted: interested, not now, wrong person, not interested, or opt-out. Opt-outs are suppressed at once. Interested replies get an answer that moves toward a meeting, in the tone you approved.

9. Handoff to sales

   A qualified lead reaches your sales team with the thread, the research note and the reason it qualified, in the place agreed on the first call: your CRM, your calendar or a shared inbox.

When two versions of a first email are worth comparing, they run side by side on comparable segments of the list, and the one that earns better replies stays. That is A/B testing on replies, not on opens, and only once a segment is large enough to read.

What you provide and what we provide

Outsourced cold email works when both sides know their part. The table splits the work as this service runs it. The right column is the done-for-you part; the middle column is what no provider can supply for you.

Three things stay with you whatever the contract says: the offer, the meetings and the feedback. If meetings with the right people do not close today, more meetings will not change that, and no cold email campaign can fix it.

Cold email services start with the sending setup

Much of what decides whether cold email reaches an inbox happens before the first send. In this page's view, a provider that cannot explain its sending setup in plain words is selling volume, not cold email services.

• Domain: mail is sent from a domain you own or control, not from a free webmail address, so authentication can pass for your company. Whether that is your main domain or a separate one is agreed on the first call.
• Authentication: SPF and DKIM on the sending domain, and a DMARC record. Google and Yahoo both require bulk senders to align the From domain with the SPF or DKIM domain.
• DMARC under RFC 9989: RFC 9989, published in May 2026, obsoletes RFC 7489. It removes the old pct tag, adds a t tag for testing a policy, and calls p=none with aggregate reports turned on monitoring mode.
• One-click unsubscribe: RFC 8058 defines it with a List-Unsubscribe header holding one HTTPS address and a List-Unsubscribe-Post header, and requires a valid DKIM signature that covers both headers.
• Warm-up and steady volume: Google tells large senders to start with a low volume, increase it slowly, send at a consistent rate and avoid sudden volume spikes.
• Monitoring: bounces, deferrals and spam complaints are watched every sending day. Google says to reduce volume when messages start bouncing or being deferred, then increase it slowly again.

When a campaign starts landing in spam anyway, the checks in emails going to spam are the ones run first: authentication, bounces, complaints, content and volume, in that order.

How the first weeks run

This is how a start usually runs here, agreed in detail on the first call. It is an outline, not a schedule. No dates or outcomes are promised, because they depend on your market, your list and the state of your sending domains.

Volume goes up only when the first segment shows low bounces, no complaint problem and replies that make sense. If it shows the opposite, the list or the copy changes first, and the volume waits.

Agreed on the first call, in writing

Several decisions are not made on this page, because they depend on your company. They are agreed on the first call and written down before anything is sent, so neither side has to remember what was said.

Rules the sending works inside

Cold email to businesses is regulated, and the rules below are stated as the primary sources state them. They are the floor, not the whole job. Nothing on this page is legal advice; for your own situation, ask your counsel.

CAN-SPAM: no exception for B2B email

The FTC's compliance guide says the CAN-SPAM Act covers all commercial messages, and that the law makes no exception for business-to-business email. Each separate email that violates it is subject to penalties of up to $53,088, according to the guide as checked.

One line in the guide matters most when you hire anyone to send for you. The FTC says you cannot contract away your legal responsibility, and that both the company whose product is promoted and the company that sends the message may be held legally responsible.

That is why the postal address, the opt-out wording and every claim in the emails are agreed with you. Your company is named in the email, and the law can treat you as responsible for it.

Gmail and Yahoo sender guidelines

Google's email sender guidelines cover mail sent to personal Gmail accounts, ending in @gmail.com or @googlemail.com, and Google's FAQ says they do not apply to messages sent to Google Workspace accounts. This service writes to work addresses at company domains and treats both providers' rules as the floor anyway.

Google's FAQ names RFC 8058 as the standard for one-click unsubscribe, says a mailto link in the body does not meet that requirement, and recommends fulfilling unsubscribe requests within 48 hours.

Those provider windows are far shorter than the legal one, so opt-outs here are handled the day the reply is read, not in a weekly batch.

EU contacts and the GDPR

If any prospects are in the European Union, the GDPR can apply even to a sender outside it. Article 3(2) covers processing of the personal data of people in the Union when it relates to offering them goods or services.

• Legal basis: Article 6(1)(f) allows processing for legitimate interests unless the person's interests or rights override them, and Recital 47 says direct marketing may be regarded as a legitimate interest.
• Notice: Article 14 requires telling people whose data was not collected from them who you are, why the data is processed and where it came from, at the latest at the first communication.
• Right to object: Article 21 gives people the right to object to direct marketing at any time, after which their data can no longer be processed for it. The right must be shown to them clearly at the first communication.
• Processor contract: when someone processes personal data on your behalf, Article 28 requires a contract that sets out the processing and binds the processor to your documented instructions.

Whether EU contacts are in scope, and how these duties are split between you and Jeluvi, is settled on the first call. This page covers the GDPR only, not every rule that can apply in each country, so check with your counsel before EU contacts are emailed.

LinkedIn, when it is a research source

Research for a cold email list can include checking LinkedIn profiles to confirm that a person still holds a role. Section 8.2 of the LinkedIn User Agreement forbids software, scripts, robots or crawlers that scrape or copy profiles and other data, and bots that add or download contacts. Jeluvi does not use those tools.

What we report, and how you judge the work

Reports show what you can check in your own CRM and inbox, not totals you have to take on trust. Whether a report arrives every week or once a month is agreed on the first call; what goes into it is listed here.

Formulas used on this page

• Bounce rate: bounced emails divided by emails sent, over the same period.
• Positive reply rate: interested replies divided by prospects contacted.
• Qualified conversation rate: qualified conversations handed over divided by prospects contacted.
• Show rate: meetings held divided by meetings booked.
• Cost per qualified meeting: the total cost of the engagement divided by qualified meetings held.

These are formulas used on this page, not industry definitions. Agree them in writing so both sides count the same way, and so the results of the cold email campaigns can be compared month to month.

Open rates are not used to judge this work. An open is not a conversation, and nobody books a meeting from one. Replies, qualified conversations and meetings held are the KPIs that show whether the campaign is working.

How cold email agencies charge, and what each model rewards

Jeluvi publishes no packages or prices; the price is agreed on the first call and written down. Whoever you buy from, it helps to know what each pricing model pays a provider to do. The right column is this page's view.

Compare offers on cost per qualified meeting held, calculated on your own results, rather than on the monthly fee. A cheap month that books the wrong meetings is the expensive option.

When doing cold email in-house is the better choice

Outsourcing is not always the right call, and a service page that says otherwise is selling. These are the cases where keeping cold email inside the company is the better choice, in this page's view.

• You already have a rep with time. Someone who knows the product, writes well and can protect a few hours a day will learn faster than any outsider.
• The product needs deep explaining. If every reply raises technical questions only your team can answer, the handoff becomes the bottleneck.
• You are still finding the market. Founders who write the first emails themselves hear what buyers say. That learning should stay inside the company.
• The list is tiny. A handful of target accounts deserves a personal email from a senior person, not a campaign.
• You want to own the skill. Outsourcing buys the work, not the habit. If cold email will be a core channel for years, build it in-house.

One reasonable path is to outsource first and bring the work in-house once the list, the copy and the handoff are proven. The emails in cold email templates are free to use either way.

Cold email outreach agency, software or an in-house SDR

Searches for cold email services return two kinds of offer: software that sends email, and agencies that do the work. This page is the second kind. Software is described here only as a category, and no tool is reviewed or ranked.

A cold email platform sends sequences from connected mailboxes, schedules follow-ups and tracks replies, and its features differ by plan and by vendor. What no platform does is decide who belongs on the list, write the email, or protect the inbox placement of your domain. That work is what a service sells.

Questions to ask any cold email agency, including us

Send the same questions to every provider you consider and compare the written answers side by side. Specific, checkable answers are worth more than a polished sales call.

• Who exactly does the work on my account, by name, and how many other clients do they carry?
• Which domains and which mailboxes will send in my name, and who owns them at the end?
• How are new mailboxes warmed up, and at what daily volume does sending start?
• Where does the list come from, and how is each address verified before it is used?
• Do I approve every email before it is sent in my name?
• How are opt-outs handled, and how fast is each one suppressed?
• What is your written definition of a qualified conversation, and will you use mine instead?
• What exactly is in the report, and can I read the raw replies?
• What do I receive at the end: the list, the copy, the reply history and the suppression list?
• What happens if a domain or mailbox runs into a deliverability problem?

Jeluvi's answers to most of these are on this page. The ones that depend on your company are on the agreed list above, and get written answers after the first call.

Red flags in a cold email offer

• A guaranteed number of meetings, offered before anyone has looked at your market.
• Pricing per email sent, which pays for the volume that harms a sending domain.
• Sending from free webmail addresses, which cannot pass DMARC alignment for your company.
• No answer about whose domains and mailboxes are used, or who owns them afterwards.
• A purchased list mailed as it is, against what Google and Yahoo tell senders.
• No opt-out line in the emails, or opt-outs handled in a monthly batch.
• Reports full of sends and opens, with no replies and no meetings held.
• Copy you are not allowed to see before it goes out in your name.

Mistakes buyers make with outsourced cold email

• Hiring before anyone can say who buys and why.
• Sending from the main company domain at full volume on day one, with no warm-up.
• Leaving current customers, open deals and partners off the exclusion list.
• Approving copy that makes claims the sales team cannot back up on the call.
• Taking meetings late, then judging the campaign on the no-shows.
• Judging after the first small send, before enough prospects have been contacted to read anything.
• Leaving the suppression list and the reply history with the provider when the work ends.

Cold email next to LinkedIn and wider lead generation

Some buyers answer email, some answer LinkedIn, and some need both before they reply at all. Jeluvi sells LinkedIn outreach as its own service, described on the LinkedIn lead generation agency page.

When one channel is not enough for your outbound, the B2B lead generation agency page covers outreach across several channels, which can include cold email and LinkedIn together. If you are not sure which fits, choose Not sure yet in the form below; the first call is where that gets decided.
