Email Marketing Agency
A full-service email marketing agency for B2B companies. We plan, build and run the campaigns, automations and cold email that turn a contact list into meetings and revenue.
Email marketing services for long B2B deals
B2B buyers take months to decide, and most of that time passes between sales calls. Email keeps you in the conversation. A good program sends the right message at each stage: first contact, evaluation, proposal and renewal.
Delivery decides everything else. A campaign that lands in spam has no open rate to improve. We warm domains, set up sender authentication and clean the lists before the first campaign goes out. For Perimed that groundwork came first, and engagement and appointments both moved inside 90 days.
Then the program has to connect to sales. Replies go to the right rep. Leads reach sales with their email history attached. Results get reported by campaign, so you can see which emails paid for themselves. Joovv's revenue from email rose 36% after we rebuilt its program.
Email marketing benchmarks for 2026
Email still returns more than most channels. But the return depends on reaching the inbox, and open rates now overstate how many people read.
Email deliverability and the Gmail and Yahoo sender rules
Since February 1, 2024, Gmail and Yahoo have required bulk senders to authenticate their email, offer one-click unsubscribe and keep spam complaints low. Google counts anyone sending more than 5,000 messages a day to Gmail accounts as a bulk sender. Email that misses these rules gets filtered or rejected, and about 1 email in 14 already lands in spam.
Every program we run starts here. We set up SPF, DKIM and DMARC on your sending domains, warm new domains and mailboxes before they send at volume, and clean lists before the first campaign. Cold email goes out from separate domains, so outbound volume never puts your main domain at risk.
Google asks senders to keep spam rates below 0.10% and never reach 0.30%. We report complaint rates and bounces every month, next to the replies and meetings they affect.
| Requirement | What it means | Gmail | Yahoo |
|---|---|---|---|
| SPF and DKIM | SPF lists the servers allowed to send for your domain. DKIM signs each email so the receiver can check nobody changed it. | Required for bulk senders | Implement both SPF and DKIM |
| DMARC policy | Tells inbox providers what to do with email that fails SPF or DKIM. | Required for bulk senders | At least p=none, and DMARC must pass |
| Low spam complaints | The share of recipients who mark your email as spam. | Below 0.30% in Postmaster Tools | Below 0.3% |
| One-click unsubscribe | An unsubscribe link that works without a login or extra steps. | Required for marketing email | Required |

Email marketing results, in our clients' words
Four email programs. Each figure comes from the client's verified Clutch review or case study.
“I've been blown away by the services of SeeResponse. They are very knowledgeable and took the time to really understand my industry and needs to help me successfully achieve my goals.”
“Since they understand both B2B tech space, SaaS and marketing in depth, there was great synergy between both teams and our workflow yielded the maximum efficiency.”
“They were always responsive and on time.”
“They're a small team but highly effective in what they did.”
Cold email, automation and SaaS email marketing
Four kinds of email program, and how to judge the results.
Cold email marketing
Cold email reaches people who have not heard of you yet. It works in B2B when the list is narrow and verified, the message is short and specific to the reader's role, and the sending setup keeps your main domain safe.
We send cold email from separate domains on Instantly or Smartlead, warm each mailbox before it sends, and route replies to your sales team. For KindKatch, outbound email campaigns produced 20,000 qualified leads and 100 booked demos.
Outbound marketing →Email marketing automation
Automation sends the right email when a contact does something: fills in a form, visits a pricing page, goes quiet, or moves to a new deal stage. Once the sequences are built, they run every day without anyone pressing send.
For Ximplifi we integrated HubSpot into the existing marketing stack and built automated workflows, landing pages and forms on top of it. Leads and sales both grew once the system was running.
HubSpot consulting →B2B email marketing
B2B email answers to a committee and a long deal. A single buyer rarely signs, so sequences speak to the person who feels the problem, the person who has to approve the spend and the person who will run the tool.
Sends are timed against the deal, not the calendar. Campaigns follow the trigger that matters: a demo that went quiet, a renewal coming up, a new hire in the role that owns the problem.
SaaS email marketing
Software companies need email after the signup as much as before it. Onboarding sequences guide new users to the first result the product promises. Activation emails respond to what a user has or hasn't done. Expansion and renewal emails go to accounts that are ready for more.
For Glewee we defined the ideal customer profile, built prospect lists and ran email drip campaigns. The platform went from no creators to more than 2,000 users in six weeks.
Which email metrics to trust
Validity's State of Email 2024 found that 70% of all opens now come from Apple's privacy proxy, which opens email automatically. An open no longer means someone read the email, so a report built on open rates overstates what a program does.
Mailchimp's benchmarks put average open rates between 27.34% and 40.55%, depending on the industry. Use them to spot a problem, such as a campaign landing in spam. Judge a B2B program on clicks, replies, meetings booked and revenue, which is how we report.
What sets email marketing agency pricing
Three things set the price. The first is how many programs run at once: a newsletter, nurture sequences, cold email, or all of them. The second is who writes and designs the emails. The third is how much setup your platform needs, such as domain warming, integrations and workflow builds.
Our retainers run $2,500 to $7,500 a month, month to month. Most email agencies on Clutch start at a $1,000 minimum project, with hourly rates from under $25 to $199. Your email platform, such as HubSpot or Mailchimp, is billed separately.
| Budget | What it usually buys | Agencies at this level |
|---|---|---|
| Under $2,500 | Template design, one-off builds and audits, per project or by the hour | Action Rocket ($25 to $49 an hour); Email Uplers project pricing |
| $2,500 to $7,500 a month | A managed program: strategy, campaigns, automation and deliverability | SeeResponse |
| $5,000+ per project | Larger ecommerce lifecycle programs | Hustler Marketing ($5,000+ minimum) |

Email marketing agency questions
Six questions, specific to email marketing.
How much do email marketing agencies charge?
Our email marketing retainers mostly run between $2,500 and $7,500 a month. Where a program lands depends on how much of the work sits with us: strategy and reporting only, or the full build of automations, campaigns and cold email. A one-off project, such as a deliverability fix or a workflow build, can cost less.
There is no minimum term. We work month to month, and it starts with a call.
How do you choose an email marketing company?
Ask who writes and who sends. Some email marketing firms hand you a strategy deck and leave the sending to your team. We do the management: the setup, the copy, the sends and the reporting.
Then ask what happens to deliverability. An agency that cannot explain domain warming, authentication and list hygiene will eventually get your mail filtered.
How does email marketing work for a B2B company?
B2B email marketing moves contacts through a buying process with messages tied to their stage. New leads get an introduction and useful material. Contacts in an open deal get case studies and answers to objections. Customers get onboarding, updates and renewal reminders.
Automation handles the timing. A form fill, a page visit or a change in deal stage starts the right sequence, and replies go straight to a sales rep.
What is the best email marketing tool for B2B?
The best tool is the one that fits your CRM, your sending volume and whether you also send cold email. HubSpot suits teams that want email and sales data in one system. ActiveCampaign and Keap suit smaller teams that want strong automation for less. Mailchimp and AWeber handle newsletters well.
Cold email belongs on its own tools and its own domains, such as Instantly or Smartlead. That keeps outbound volume from putting your marketing email at risk.
If you already pay for one of these platforms, the best tool is usually the one you have. We build on it and only suggest a change when the platform is the thing holding the program back.
How do you build a B2B email list?
A B2B list comes from two sources. Opt-in contacts come from useful offers on your website and at events: guides, webinars, calculators and newsletter sign-ups. Outbound contacts are researched against your ideal customer profile and verified before any send.
The two lists get different emails. Opt-in contacts can receive newsletters and nurture sequences. Outbound contacts get short, relevant cold sequences sent from separate domains.
How does B2B email automation work?
Automation runs sequences that start when a contact meets a condition you set. A demo request, a pricing page visit or a deal moving to a new stage can each trigger a different sequence. The platform sends each email on schedule and stops when the contact replies or books a meeting.
We build these workflows inside your platform, test them before launch, and report on what each sequence produces.
