Schedule follow-up emails from Trello cards
Turn Trello due dates into scheduled follow-ups. Set reminders, save your templates, and let Trello automation send the email for you.
Sending that first email is often the easy part, it’s the follow-up that slips, because remembering to chase up on someone who hasn't replied is exactly the kind of task that gets lost when your week goes off the rails. That’s why it’s useful to know how to turn Trello cards into scheduled follow-ups: using due dates as reminders, Saved Replies for the emails you send over and over, and Trello automation (Butler) rules that do the sending for you.
Start with due dates as chase reminders
If your outreach already lives on a Trello board with Email for Trello, every prospect, invoice, or pending request is a card with its email thread attached. That gives you a follow-up system before you automate anything: when you send an email and expect a reply, set a due date on the card for the day you want to follow-up on it.
Trello does the remembering for you: cards show a due-soon badge as the date approaches, flag as overdue once it passes, and surface in your Today view. When the day arrives, you open the card, see the whole conversation in one place, and send the nudge from right there.
It's worth running this manually for a week or two before you add rules, because you'll learn what your natural rhythm is (should you follow-up every three days? Once a week?) and that number is what you'll feed into Trello automation later.
Write your follow-ups once as Saved Replies
Follow-up emails are repetitive by design. "Just checking in on the below", "Bumping this to the top of your inbox", "Wanted to make sure this didn't get lost." If you're typing a variant of the same message every time, store it once as a Saved Reply, and reuse it on every card.
Give each template a short keyword: chase-1 for the gentle nudge, chase-2 for the firmer one, invoice-reminder for overdue payments. In the email editor, typing # brings up your Saved Reply list, so sending a follow-up manually takes seconds.
Here's a chase-1 that works for most first nudges:
Hi {%recipientFirstname || 'there'%},
Just checking you saw my last email. I know inboxes get busy, so I'm giving this one a nudge in case it slipped through.
Happy to answer any questions, and if the timing isn't right, let me know and I'll circle back later.
Best, {%senderFirstname%}
💡 TIP Saved Replies are shared across everyone on the board, so the whole team chases with the same wording. Here's how to set up Saved Replies in Email for Trello.
Let automation send the follow-up for you
With reminders and templates in place, the last manual step is the send itself, and Trello automation can take that over. Email for Trello sends an email whenever a comment starting with @reply or @email is posted on a card, and Butler can post that comment when a due date arrives. Like Saved Replies, comment-based sending and Butler email automation are part of the Pro plan.
The full journey, from first email to chase, takes two rules:
You send the opening email from the card, then move the card to a list called "Awaiting reply".
A schedule rule books the chase: when a card is moved into "Awaiting reply", set the due date in 4 working days.
A send rule fires it: the moment a card in "Awaiting reply" is due, post the comment @reply #chase-1 and move the card to "Chased".
The @reply #chase-1 comment sends your chase-1 Saved Reply to the contact on the card's thread, variables filled in. Drag a card into the list and the chase is booked; four days of silence later, it's sent.
As written, this chases exactly once. After the send rule fires, the card waits in "Chased" with no new due date, which is the right default for a quote, an intro, or a first invoice reminder. This due-date-to-email mechanic is the engine behind a lot of Trello email workflows, and our guide to automating emails in Trello based on due dates walks through it step by step, with worked examples for support check-ins and invoice reminders.
Stop chasing the moment they reply
An automated follow-up sent to someone who already answered is worse than no follow-up at all, so build the exit before you switch the sending on.
Email for Trello posts every inbound email onto the card as a comment with a recognizable email prefix, which means Butler can react to a reply arriving. Add one rule: when an inbound email comment is added to a card, remove the due date and move the card to "Replied". The due date disappears, the send rule never fires, and the card is waiting for a human response instead of a robot nudge.
This is the piece that makes scheduled sending safe. The chase only continues while the silence does.
💡 TIP Butler tells inbound and outbound emails apart by the prefix on the comment. Our guide to automating email with Trello automation covers the setup, including how to target inbound emails specifically.
Scale it from one nudge to a full sequence
If your outreach is more structured than a single follow-up, the same three ingredients chain into a multi-touch cadence: one list per touch, one send rule per list, and a fresh due date set at every step. A card that stays silent walks across the board from nudge to nudge until it reaches a polite breakup email. We've written up the full board layout in our guide to running a cold outreach sequence entirely from Trello.
Two checks before you rely on it
Trello has automation quotas that depend on your plan, so a high-volume board can hit the ceiling mid-month. Check your usage in Trello's automation settings before you wire up a long list of cards.
A scheduled email is also still a real email from you. Read each template the way a recipient on their third nudge would, and give every card a ceiling: after the breakup email, the chase ends.
Set the date, then let go
A follow-up system only has to do one thing: make the chase happen without you holding it in your head. Due dates get you there manually, Saved Replies remove the retyping, and Trello automation removes the remembering entirely.
