Single tasks are only half of it. The agent on your Listmonk server can also wire together small pipelines — cron jobs, API calls, shell scripts — so things happen on their own while you do something else. These ten workflows run unattended once the agent builds them, and they use parts of Listmonk most owners never touch: the REST API, the transactional send endpoint, and the Postgres database underneath. Each one is built from plain files you can read and keep.

1. A Welcome Drip for New Signups

Someone confirms their subscription and then hears nothing for a month; a short sequence in week one changes that and lifts open rates on everything you send later. The agent writes a script that polls for newly confirmed subscribers, sends the day-zero welcome through Listmonk’s transactional API, then queues the day-3 and day-7 emails, and hangs it off cron with a log you can check. “Set up a three-email welcome drip — immediate, day 3, day 7 — for everyone who joins the ‘newsletter’ list, using the ‘welcome’ template.”

2. A Weekly Digest That Drafts Itself

Every week someone copies blog posts into a newsletter by hand, and it takes an hour it should not take — which is why most newsletters quietly become monthly. The agent builds a cron job that pulls the latest posts from your WordPress site’s REST API, fills a Listmonk template, and creates the campaign as a draft with everything already in place. You only review and press send. “Every Monday at 8am, pull last week’s posts from my WordPress site and create a draft digest campaign for the ‘newsletter’ list.”

3. Win Back Subscribers Who Went Quiet

Lists decay, and the subscribers who never open are the ones most likely to mark you as spam — which hurts delivery to everyone else. The agent sets up a monthly job that finds subscribers with no opens in 120 days, moves them to a ‘winback’ list, sends a re-engagement campaign to that list, and blocklists the ones who still do not respond, so your sender reputation stays clean. “Monthly, find subscribers with zero opens in the last 120 days, add them to the ‘winback’ list, and send the re-engagement template to that list.”

4. Follow Up After a Purchase

Order confirmations are transactional, but the “how is it going” email three days later is the message almost nobody sends — and it is where reviews and repeat orders come from. The agent writes a bridge your store can call, or a nightly sync, that adds buyers to a Listmonk list with the order total stored as an attribute, then sends a timed follow-up campaign that can mention what they bought. “When an order ships in WooCommerce, add the customer to the ‘buyers’ list with their order total as an attribute, and send the follow-up template three days later.”

5. Birthday and Anniversary Emails

Dates sitting in your subscriber attributes are free goodwill if anything ever acts on them; otherwise they are just rows in a JSON blob. The agent creates a daily cron job that selects subscribers whose birthday attribute matches today, sends the templated message through the transactional API, and sets a flag on each subscriber so nobody gets two in the same year. “Every morning at 7am, send the ‘birthday’ template to subscribers whose birthday attribute is today, and never mail the same person twice in a year.”

6. A Custom Form That Feeds Listmonk

Listmonk’s built-in subscription form works, but it looks like Listmonk rather than your business, and the styling options are limited. The agent builds a page on your server with fields for name, email, and interests, posting to a tiny relay script that calls Listmonk’s public subscription API — with double opt-in and attribute capture handled, and the confirmation email styled the way you want. “Build a signup page at /subscribe on this server that captures email, name, and interests, and subscribes people to the ‘newsletter’ list with double opt-in.”

7. Nightly Bounce and Complaint Cleanup

Bounces and spam complaints quietly poison deliverability while nobody is watching, and by the time you notice, your domain is already throttled. The agent sets up a job that reads the bounce records Listmonk already keeps, blocklists hard bounces and complainers automatically, and emails you a short summary of what it suppressed and why, so you stay informed without babysitting it. “Every night, blocklist hard bounces and complaints from the last 24 hours, and email me a summary of what was suppressed and why.”

8. A Stats Digest After Every Campaign

You should not have to remember to check how a send went — the numbers exist, but they sit in the admin panel until someone goes looking. The agent wires a script that polls campaign status, and when a run finishes it pulls sent, delivered, opened, clicked, and unsubscribed counts, then mails you a tidy summary next to the previous campaign’s numbers so you see the trend, not just a snapshot. “When a campaign finishes, email me a summary with this campaign’s stats side by side against the previous one.”

9. A Pre-Flight Check Before Big Sends

Sending 50,000 emails with a typo is a memorable mistake, and it is exactly the kind of thing that happens when nobody has a checklist. The agent builds one that runs before any large send: SPF, DKIM, and DMARC records present on the sending domain, an unsubscribe link present in the template, the from-address domain matching, and the list size looking sane — and it refuses to give the all-clear if anything fails. “Before any campaign over 10,000 recipients goes out, verify DKIM and SPF on my domain, confirm the template has an unsubscribe link, and report anything wrong.”

10. Backups With a Restore Test

A newsletter list you spent five years building lives in one Postgres database, and losing it — or only discovering your backup is corrupt when you need it — is not an option. The agent sets up a nightly pg_dump plus copies of config.toml and the media folder to offsite storage, keeps 30 days of history, and — the part everyone skips — a monthly restore of the latest backup into a throwaway container to prove it actually works. “Back up the Listmonk database, config, and media nightly to my S3 bucket, keep 30 days, and once a month restore the newest backup into a scratch container to verify it.”

Each workflow is a few files and a cron line that the agent can show you, explain, or take away again if it does not earn its place. Start with one, watch it run for a week, then add the next. Listmonk on OpenSysLab
