Email marketing, written and sent for you.

An email marketing agency that writes your newsletters, builds your follow-up and keeps your list clean. One team. One flat monthly fee.

Loved by founders and service businesses
The problem

Many businesses sit on a list they never email.

You have years of names. People who asked for a quote. People who bought once. People who downloaded a guide and never heard from you again. Every one of them already knows your name, and most have not heard from you since.

When email does go out, it tends to go wrong in the same ways:

Doing it yourself, the weekly email is the first thing to slip when you get busy. A freelance copywriter can write a good email, but they cannot build the automations, clean the list or connect it to your CRM. And an email tool on its own does not write anything.

As an email marketing agency inside a full marketing plan, we do all of it: the writing, the sending, the automations, the list and the rules.

What you get

What our email marketing includes.

Newsletters

A regular email to your list, written in your voice. Useful first, selling second: tips, news, stories from your work, and a clear next step when it fits.

Campaigns

Emails for a launch, an offer or a season. Planned, written, sent to the right segment, and checked afterwards to see what it brought in.

Automatic follow-up

The emails that go out on their own: a welcome for new leads, follow-up after a quote or enquiry, and a nudge after a booking or a purchase. Texts too, where they fit.

Nurture sequences

A series of emails for leads who are interested but not ready yet. It answers their questions and keeps you in mind until the timing is right.

Reactivation

Win-back emails for past customers and cold leads who have gone quiet. People who bought before already know you, which makes them easier to win back than a stranger.

List hygiene and the rules

Segments so each person gets the right emails. Regular clean-ups of dead addresses. A working unsubscribe link and your address on every marketing email.

Example requests

What does an email marketing agency do?

An email marketing agency plans, writes and sends your marketing emails, and builds the automatic emails that follow up with leads and customers. A good one also looks after your list and makes sure your emails follow the rules, so they keep landing in the inbox.

In practice, the work falls into four parts:

Strategy

Who is on your list, what each group needs to hear, and how often.

Writing and design

Subject lines, the email itself and a clear next step.

Automation

Emails that send on their own when someone joins, books, buys or goes quiet.

List care

Segments, clean-ups, unsubscribes and the rules for each country you send to.

Email works best when it is joined to everything else. The welcome email should match the ad and the landing page. The follow-up should stop when someone books. That is why we run email with your CRM and automations, not as a separate job.

Guide · 02

Email marketing services: what should be included?

Full email marketing services should include writing, sending, automations, list care and reporting. If a provider only writes the emails, you still need someone to build the follow-up, clean the list and track what it earns.

Here is a checklist to hold any provider to, including us:

Step 1

A welcome email or sequence for every new lead.

Step 2

Follow-up for quotes, enquiries and bookings.

Step 3

A nurture sequence for leads who are not ready yet.

Step 4

A regular newsletter.

Step 5

Campaigns for launches, offers and seasons.

Step 6

Win-back emails for people who went quiet.

Step 7

Segments, so customers and leads get different emails.

Step 8

List clean-ups and working unsubscribes.

Step 9

A monthly report on what email brought in, not just opens.

We cover all nine as part of one plan. If you want to see how the pieces fit, we wrote about building an email system that works while you sleep.

Newsletters, campaigns and automations: what each one is for

Newsletters keep you in mind, campaigns sell something specific, and automations follow up with each person at the right moment. You need all three, because each does a job the others cannot.

Newsletters

A newsletter goes to your whole list, or a big part of it, on a schedule. Its job is trust. If every email is useful, people keep opening, so they are still there when you have something to sell.

Campaigns

A campaign is a short burst of emails with one goal: fill a workshop, launch a service, move a seasonal offer. It works best sent to the people most likely to care, not to everyone.

Automations

Automations send based on what a person does. They join, so they get a welcome. They ask for a quote, so they get follow-up. They book, so they get a reminder. They go quiet, so they get a check-in. These run every day without anyone pressing send, and they keep working long after a campaign ends. For the setup side, see our guide to nurture sequences that convert.

Guide · 04

How often should you send marketing emails?

Send as often as you can send something useful, on a rhythm you can keep. For most small businesses we suggest a newsletter every week or every two weeks, plus automations and the odd campaign.

Too rarely, and people forget who you are, so your next email looks like spam to them. Too often with nothing to say, and they unsubscribe. The fix is not a magic number. It is a steady schedule, emails worth opening, and watching replies and unsubscribes to see how your list reacts.

Automations are different. They send when the person acts, so timing follows them, not your calendar.

Guide · 05

The email marketing rules you need to know

In the US, you can email people without asking first, but every marketing email must be honest, include your postal address and a working way to opt out. In Canada, the UK, the EU and Australia, you mostly need consent before you send marketing email at all.

This is general information, not legal advice. The main points:

US (CAN-SPAM)

No false headers or misleading subject lines. Say it is an ad. Include your physical address. Tell people how to opt out, and the FTC says you must honour opt-outs within 10 business days. The FTC also says the law makes no exception for business-to-business email.

UK and EU

Opt-in. There is an exception for your own customers, for similar products, if they were given a chance to say no when you collected their details.

Canada (CASL)

Opt-in, with some limited exceptions.

Australia (Spam Act)

Opt-in, and strict. A one-off purchase on its own does not count as consent.

Two points catch people out. First, a free download on its own does not give you consent to send marketing in the EU or Australia, so ask clearly, with a box that is not ticked for them. Second, the fines regulators hand out are mostly about broken or hidden unsubscribes, and about marketing slipped into receipts and order emails. Keep those emails clean, or treat them as marketing with all the rules.

One more thing. The FTC says you cannot contract away your responsibility when someone else sends email for you. So we set your emails up to follow the rules, and you still sign off on them.

Guide · 06

List hygiene: why a smaller list can do better

A clean list gets more of your emails into the inbox. Mail providers watch bounces, spam complaints and how many people ignore you, and they send more of your mail to spam when those look bad.

Gmail now asks every sender to authenticate their domain, and asks bulk senders to offer one-click unsubscribe and keep spam complaints below 0.3%, according to Google's sender guidelines.

So list care is not a nice extra. It is what keeps email working:

Guide · 07

How much does an email marketing agency cost?

Most email marketing agencies charge a monthly retainer or a price per email or sequence, and you pay for the email software on top. Prices vary a lot with how many emails you send and how much automation you need.

Before you sign with anyone, ask what is included. Does the fee cover writing, design, automations and list care, or just the newsletter? Is there a contract? Who owns the list and the templates if you leave?

Our answer: $4,995 USD a month, flat, with no setup fee and no contract. It covers email marketing and everything else in the plan, including ads, landing pages, SEO and AI chat. The CRM comes with the plan, and your emails send from it. See full pricing.

Is Havstock the right email marketing agency for you?

We are a good fit if you have a list, or leads coming in, and nobody has time to email them well. We are a strong fit if you also want the ads, pages and follow-up run by the same team.

We are not the right fit if you only want a newsletter designer and nothing else, or if you want someone to post on your social media too. We do not do organic social posting. Book a 15-minute call and we will tell you honestly whether it makes sense.

FAQ

Questions. Answered.

How much does your email marketing cost?

$4,995 USD a month, flat. That covers email and everything else in the plan: ads, websites, CRM, SEO and AI chat. No setup fee. Usage fees for texts, emails and AI chat are also on you. They are small, and they go on a card you keep on file. See full pricing.

Do we need to buy separate email software?

No. The CRM comes with the plan and it sends your emails, so you do not need a separate email tool.

Who writes the emails?

We do, in your voice. Send us a voice note or a few bullet points, or let us suggest the topic. You approve every email before it goes out.

Can we email everyone on our list?

It depends where they live and how you got their address. In the US you can email without asking first, as long as you follow the opt-out rules. In the UK, the EU, Canada and Australia you mostly need consent. We help you sort the list early on. This is general information, not legal advice.

Do you send texts too?

Yes, where they fit. Follow-up by text works well for bookings, reminders and missed calls. It runs from the same CRM.

Who owns the email list?

You do. Your list, your data and your templates are yours. If you leave, they stay with you.

Is there a contract?

No. It is month to month and you can cancel anytime. Try it for a week, and if you are not happy, get 75% back.

What don't you do?

Filming, photo shoots, video editing, print and organic social posting. Custom software is quoted separately.

You run the business.
