Newsletter, reminder, app email, thank-you: everything leaves from Sendlenk, signed by your domain.

You pay for who you email.Not your list.

Your list is stored without limit. Each month, only the contacts you emailed count, 10 sends per contact included. And your emails arrive, by design, not by luck.

The screens show sample data: Mélidore, Camille and Nora are made up.

SendlenkDeliverability

Not in spam. By design.

Sendlenk prepares your subdomain, signs it, reads your DMARC policy, warms up gently over 10 days, and stops before your reputation gets hurt.

DKIM, aligned Return-Path, DMARC read before the first send
Imported contacts: 500 on day one, then double each day
Automatic pause from 4% bounces or 0.1% complaints

SendlenkTwo emails

The letter and the app email, in one place.

Your monthly newsletter and your app’s “password changed” leave from the same tool, the same domain, with the same reputation. A transactional API for one, an editor for the other.

LenKoreA LenKore tool

One account.The other tools recognise you.

Sendlenk will know who opens and who clicks. With the same LenKore account, the other tools will tell it the rest:

The LenKore suite

Not in spam.By design, not by luck.

Most tools hand you the keys and let you burn your domain. Sendlenk ships with guardrails, so good deliverability is the default.

Your domain, ready to sign

On your own subdomain, Sendlenk generates DKIM signing and an aligned Return-Path, checks everything and reads your DMARC policy before the first send. If there isn’t one, it suggests one.

A 10-day warm-up

Your confirmed subscribers go out right away. Imported contacts: 500 on day one, then double each day as long as things look healthy. It ramps up on its own.

A pause before the penalty

At 4% bounces or 0.1% complaints in 24 hours, sending stops and you’re told, before Gmail or Outlook step in.

A clean list

At import, malformed, mailbox-less or disposable addresses are set aside, along with duplicates and addresses that already unsubscribed from you. Above 5% invalid addresses, the import is blocked.

Fairer numbers

Known automated opens, like Apple Mail preloading or security scanners, are set aside by default.

One-click unsubscribe

The headers Gmail and Yahoo require are added for you, and the unsubscribe link lets people pick their topics instead of leaving altogether.
