You own the list
Social reach is rented; an algorithm can zero it overnight. Your email list is a portable asset no platform can take away.
No ad auction, ever
No bidding wars, no rising ad costs, no platform policy changes. Your list is something you own, not reach you rent.

Everything you need to send today
Write, send, segment, measure. Automated journeys come next, in the same workspace.
AI campaign generation
Describe your goal in one line. You get three subject lines, the body and the call to action in your brand voice, ready to edit and send.
SPF, DKIM and DMARC, generated for you
We create the records, you paste them into your DNS once, and we keep checking them. You send as you@yourbrand.com, never from a shared sender.
60-second Quick Send
From idea to sent in under a minute, for the days you need to send now instead of building a campaign in a drag-and-drop editor.
Audience and segments
Import a CSV, tag contacts and build segments by tag, status or engagement, with consent tracked for every contact. Bounces, complaints and unsubscribes are suppressed for you.
Real-time analytics
Opens, clicks and bounces for every campaign in one dashboard. Clicks come first, because that's the number that pays you.
Domain health
Authentication status, bounce and complaint rates against the limits Gmail and Yahoo enforce, and a warm-up plan for new domains. When something drifts, you get the fix in plain language.
Where the revenue actually comes from
Five numbers, multiplied. Move any one of them and revenue moves with it.
Revenue equals list size times open rate times click rate times conversion rate times order value.
Seven levers move these five numbers. Below, each one is paired with the Sendlark feature that moves it, and when it ships.
Direct conversion campaigns
Launches and promos to a warm list convert at multiples of cold traffic.

Deliverability

Segmentation

What is Sendlark?
An email marketing tool for small teams. You describe a campaign in one sentence, Sendlark writes the email, sends it from your own domain and shows you opens, clicks and bounces. Automated journeys and send-time optimisation come next.
Who is it for?
D2C brands, marketplace sellers, agencies and small teams who want to email their customers regularly but don't have a marketer or the time to build every campaign by hand.
When can I start using it?
We're building it now and will invite the waitlist in order, founding members first. We'll email you as soon as your invite is ready.
What does it cost?
You pay for the emails you send, not the size of your list. Free: 1,000 emails a month and up to 2,500 contacts. Starter: $19 a month for 10,000 emails. Growth: $49 a month for 50,000 emails and 3 seats. Team: $99 a month for 100,000 emails and 5 seats. Every paid plan has unlimited contacts, and every plan sends from your own domain.
What do founding members get?
Pay a $29 one-time deposit and get $40 of credit toward any paid plan (Starter, Growth or Team), your launch price locked for 12 months, and an earlier invite. It's not a subscription, and you can get the full $29 back any time before your account is set up.
Do I need my own domain?
Yes, and it's what keeps you out of spam. Gmail and Yahoo now require bulk senders to authenticate their domain. Sendlark generates the SPF, DKIM and DMARC records for you; you paste them into your DNS once and we keep checking them.
Can I bring my existing list?
Yes. Import a CSV of people who agreed to hear from you. Sendlark tracks consent for each contact and automatically stops sending to bounces, complaints and unsubscribes.
How is this different from Mailchimp or Klaviyo?
Those tools start with a template editor and leave the writing, the sender setup and the deliverability checks to you. Sendlark starts from one sentence and handles those parts, so a campaign takes minutes instead of an afternoon.
Is my data safe?
We follow the EU GDPR and Thailand's PDPA. Your contacts are only used to send your campaigns, never sold or shared, and every plan can export or delete its data at any time. See our privacy policy for details.
Your next campaign is one sentence away.
