Email platform implementation
Klaviyo setup services
A Klaviyo setup service gets the platform ready to send. The work is worth paying for when it covers the parts that are easy to get wrong: authenticating a branded sending domain, connecting your shop or systems and checking the data arrives, importing contacts with their consent status intact, building lists and segments that will be useful, designing sign-up forms that collect consent properly, and building core flows that are tested with real events. A setup that imports every contact ever collected and switches on default flows without testing may look quick but can damage deliverability and break consent rules.
This guide covers what to expect, questions to ask, warning signs, deliverables and handover. LetGetGrow sets up and manages Klaviyo and Mailchimp, including flows, templates, integrations and migrations, with the scope, cost and timeline set out in a custom quotation.

What a setup should include
| Item | Why it matters |
|---|---|
| Branded sending domain | Emails come from your brand |
| Authentication check | Meets inbox provider requirements |
| Integration check | Profiles and events arrive correctly |
| Consent-aware import | Only permitted contacts receive marketing |
| Lists, segments and forms | Structure for future campaigns |
| Tested core flows | Automations work from day one |
Imports and consent
Ask how the provider will decide which contacts to import as subscribed. The answer should involve your records of how people opted in. ICO guidance says marketing emails to individuals need consent or the soft opt-in conditions, and Klaviyo's help notes that list imports do not trigger double opt-in, so the provider cannot rely on Klaviyo to confirm consent for imported contacts.
Warning signs
Import everyone
Consent ignored; deliverability at risk.
No sending domain
Emails appear to come from Klaviyo.
Default flows switched on untested
Broken links or wrong timing.
Account in their name
You may lose data and history.
Authentication
Gmail's sender guidelines require SPF or DKIM for all senders and SPF, DKIM and DMARC for bulk senders, plus one-click unsubscribe. Ask the provider to confirm these are in place and to work with whoever manages your domain's DNS.

Illustrative example — not a client case study
Situation: A gift shop has contacts from its till system, its website and a past competition.
- The provider asks how each group opted in; competition entrants who did not agree to marketing are left out.
- Website customers who accepted marketing are imported as subscribed; others are kept as non-subscribed profiles.
- Welcome and abandoned cart flows are tested with test orders before launch.
What this shows: The shop launched with a smaller but permitted list. This example is illustrative.

Ownership
The Klaviyo account should be created in your business's name, with your billing, and the provider given a user role you can remove.
Fees
Setup is usually a one-off fee. Template design, extra flows and ongoing campaigns may be priced separately. Klaviyo's own subscription is paid to Klaviyo.
Integration checks
Ask how the provider will confirm that customer profiles and events arrive correctly after connecting your shop. Klaviyo's Shopify data reference lists events such as Checkout Started, Placed Order and Fulfilled Order. A test order traced through to a profile shows the data flows work before any automation depends on them.
Segments worth having
A good setup includes a few useful segments from the start: engaged subscribers, recent buyers, repeat customers and people who have not opened in a long time. Klaviyo describes segments as dynamic groups defined by conditions, so they update themselves as people's behaviour changes.
Forms and consent wording
Ask to see sign-up forms and consent wording before they go live. Consent should be a clear action, and the form should say what people will receive. You remain responsible for how consent is collected.
Handover
Ask for notes covering the sending domain, integrations, segments, forms and each flow's trigger, timing and conditions, so your team or another provider can maintain the setup.
Questions to ask
Ask how the provider will set up and verify the sending domain, which data the integration will bring in and how it will be checked, how imported contacts will be split by consent, which segments and flows are included, how each flow will be tested and what documentation you will receive. Clear answers show a careful setup.
