A sequence is a drip campaign — ordered messages delivered on a schedule after a contact subscribes. You write the messages once and set how many days apart they go out, and DMLY sends them one at a time to each contact who joins. The clock starts when that contact subscribes, so every contact sits at their own point in the run: someone who enquired this morning is on day 0 while someone who enquired last week is on day 5. Sequences run on WhatsApp, Facebook, Instagram, Telegram, SMS, Live Chat and TikTok. What a step can send, and when it arrives, differs by channel — that is the part worth reading before you build.

​
Sequence or broadcast?

This is the choice people get wrong, and it costs a wasted campaign either way.

Broadcast

One message, to many contacts, now. You pick the audience and you pick the moment. Everyone gets it at the same time. Use it for news: a sale, a closure, a new opening.

Sequence

Several messages, to one contact, over days. The contact’s own subscription date starts the clock. Use it to follow a person through a stage — a welcome, a nurture, a follow-up.
A rough test: if the message makes sense only today, broadcast it. If it would make just as much sense to someone who enquires next month, put it in a sequence and let a flow subscribe them.

​
Sequence or flow?

A flow is a conversation. It reacts to what the contact does right now — they message you, they tap a button, they answer a question — and it runs in seconds. A sequence is a calendar. It doesn’t react to anything; it just sends step 2 a day after step 1 whether the contact replied or not. Use a flow for the conversation, and have that flow subscribe the contact to a sequence for the days that follow.

​
What you’d use one for

  • Welcome series after a first enquiry. Someone messages you for the first time. Day 0 thanks them and answers the obvious question, day 1 shows what you do, day 2 invites them to book. Every new enquiry gets the same run without you writing it again.
  • Lead nurture. An enquiry that didn’t book stays warm for a few days — proof, prices, an offer — instead of going cold in the Inbox.
  • Post-appointment follow-up. Day 1 checks how they got on, day 2 asks whether they’d recommend you, day 3 nudges them to rebook.
  • Win-back. A contact who has gone quiet gets a short run: we’ve missed you, here’s what’s new, here’s a reason to come back.

​
What a step can send

A step is one message. You can’t attach an image, file or voice note to it. Beyond that, the step editor changes with the channel the sequence belongs to.

​
On WhatsApp

A Send as picker sits above each message with three choices:
  • Standard send — Free-form message — delivers inside the 24-hour WhatsApp window.
  • Utility template — Pre-approved utility template (order updates, reminders) — delivers outside the 24-hour window.
  • Marketing message — Pre-approved marketing template — delivers outside the 24-hour window.
Choosing either template option swaps the message box for a Template picker holding your approved templates of that category — the same ones your broadcasts use. Pick one, fill in its Template variables, and the preview shows what the contact gets. Only approved templates appear; if the list is empty, Manage templates takes you to submit one. Templates are what make long WhatsApp sequences work — see what arrives, and when.

​
On Facebook and Instagram

Send as offers two choices:
  • Standard send — Inside the 24-hour messaging window.
  • Human agent — Rides Meta’s live-agent allowance — up to 7 days after the contact’s last message. For agent-style follow-ups, not bulk marketing.

​
On Telegram, SMS, Live Chat and TikTok

There’s no Send as picker — there’s only one way to send, so the step is just your Message.

​
Where sequences live

Go to Automation in the sidebar, then select Sequences. There is no sidebar entry of its own. You can also reach it from Manage sequences → inside a flow’s Sequence step. The list shows each sequence’s Sequence, Channel, Steps, Subscribers, Status and Updated. Subscribers is how many contacts are working through it right now — it goes down as people finish, not up. It is not a lifetime total.
A sequence belongs to one channel: the one you had selected when you created it. The Channel field is read-only and can never be reassigned — Sequences belong to the selected profile. The list only shows sequences for the channel you currently have selected, so if a sequence seems to have vanished, check the channel selector before you rebuild it.

​
Build a sequence

1

Create it

Select the channel the sequence should belong to, then go to Automation → Sequences → New sequence. Give it a Name — only you and your team ever see it, so name it after the job it does: Welcome nurture, Post-visit follow-up.A new sequence starts with two steps ready to fill in, and is Active from the moment you create it.
2

Set the Day for each step

Each step has a Day, a whole number of days from zero up. Day 0 means the step is due as soon as the contact subscribes; day 3 means three days later.What sets the wait between two steps is the gap between their Day numbers, counted from when the previous step really sent. So 0, 1, 3 means: on subscribing, one day later, then two days after that. Keep the numbers climbing.
3

Set the hours

From and To set the times of day a step is allowed to go out — 09:00 to 20:00 by default. A step that comes due before From waits for it; a step that comes due after To moves to From the next day. It stops you messaging someone at 3am.These times are read in UTC, not your local time. If you are not on UTC, shift them.
4

Write the message

Write your Message, or pick a template — see what a step can send for what your channel offers. You can drop contact details into free-form text: {{first_name}} becomes the contact’s first name when it sends.
5

Add the rest

Add step appends another one, a day after the last. You can move steps up and down and remove them, and the Timeline panel shows the run in order as you build.Every step needs a message or a template. An incomplete one blocks saving: Step {number} is incomplete — add a message or pick a template.
6

Save

Select Create sequence (or Save sequence when editing). Nothing sends yet — a sequence sits idle until a flow subscribes someone to it, exactly as the page says: Delivery starts when a contact is subscribed via the flow builder’s Sequence step.
Moving a step up or down does not renumber its Day. Because the wait is the gap between consecutive steps, moving a day 5 step above a day 1 step leaves no gap at all — that second message goes out to real contacts as soon as the first one lands and the From–To hours allow. After any reorder, read the Timeline top to bottom and check the days still climb.

​
How contacts join

There is exactly one way into a sequence: the Sequence step in the flow builder. There is no button on a contact, no bulk action, no import, and no way to subscribe someone by hand.
1

Open the flow that should feed it

Go to Automation and open or create a flow on the same channel the sequence belongs to. A flow only ever offers sequences from its own channel — if your sequence isn’t in the list, it’s on a different one.
2

Add the Sequence step

In the flow builder, the Sequence step is in the Logic group. Drag it in and connect it where the contact should join — after they reply to your greeting, after they pick an option, after they’ve been tagged as a lead.
3

Point it at the sequence

Select the step and pick your sequence under Choose a sequence…. That’s the only thing it configures. The panel says it plainly: Subscribes the contact to the selected drip sequence.
4

Publish the flow

The step has one output and the conversation carries straight on through it — subscribing doesn’t pause or end the chat. From then on the schedule runs in the background.
Subscribing the same contact twice does nothing: a contact already working through a sequence is never restarted or doubled up. But a contact who has finished it, or whose run was stopped, starts again from the first step — which is what you want for a win-back someone can go through more than once.

​
What arrives, and when

Most channels only let you message a contact for a while after they last messaged you. A sequence holds to that line, and on Meta channels it decides more about what arrives than your schedule does. A step that comes due when the channel won’t carry it is held, not lost. DMLY retries it about once an hour, up to 48 times — roughly two days. If the contact messages you in that time the window reopens and the held step goes out, still in order. If they never do, that contact’s run stops there and no further steps are sent. The clock restarts every time the contact messages you.
On WhatsApp, this is the whole argument for templates. A free-form day-7 step only reaches contacts who are still talking to you; a template step reaches everyone. If a WhatsApp sequence has to run past the first day or two, build the later steps from approved templates. See WhatsApp rules and limits.
On Telegram, SMS and Live Chat there’s no window at all — every step sends on the day you set it, however long the contact has been quiet.
On Facebook and Instagram, the flow builder’s Marketing Opt-in step asks a contact for permission to message them once outside the window. If they accept, one held step can ride that permission — but only one, and only if you asked before the window closed.
A sequence delivers on whichever channel the contact actually uses, not the sequence’s own channel. For a free-form step that’s helpful — it still reaches them.But a template step is silently dropped. A step only counts as a template when the contact’s own channel is WhatsApp; for anyone else that step has no free-form text to fall back on, so it’s skipped and the run moves on. Nothing tells you.So if you build the recommended template-based WhatsApp sequence, subscribe only contacts who reached you on WhatsApp. Mixing channels into it quietly loses steps.

​
Pausing and resuming

Each row in the Sequences list has an Active / Paused switch in the Status column. Turn it off and Sequence paused — steps stop sending until you resume it. Pausing genuinely freezes delivery. Contacts already subscribed stop receiving steps immediately, and nothing is burned while you’re paused: nobody is dropped for a closed window, and nobody misses a step. Turn it back on and Sequence resumed — every contact picks up exactly where they left off, within a minute, in order.
Pausing doesn’t stop new contacts joining. A paused sequence still appears in the Sequence step’s picker, and a flow pointing at it keeps subscribing people — they just queue up behind step 1 until you resume. To stop new contacts joining, remove or repoint the Sequence step in the flow that feeds it, and publish.

​
How contacts leave

A contact stops receiving a sequence when any of these happen:
  • They finish it. The last step sends and the run completes.
  • The window stays shut. On a windowed channel, no message from them for the roughly two days DMLY spends retrying a held step — see what arrives, and when.
  • They opt out. A contact who replies with a stop keyword is added to your suppression list, and no further sequence steps are sent to them. On WhatsApp, Facebook, Instagram, SMS, Live Chat and TikTok that means stop, stopall, stop all, unsubscribe, cancel, quit, end, opt out or optout. Telegram recognises a shorter list — /stop, stop, unsubscribe and cancel only, so quit, end and opt out don’t opt anyone out there.
  • A flow unsubscribes them. The Unsubscribe Contact step does the same thing deliberately, and stops every sequence run they are in straight away.
  • The bot is paused on them, or they’re blocked. Handover to Human pauses the bot for that contact, which ends their sequence run at the next due step. Resume bot replies does not bring the run back — only the Sequence step can, and it starts them from the beginning.
A normal reply does not take someone out of a sequence. If a contact answers your day 1 message and books, they still get day 2 and day 3 unless something above stops them. Build the exit into the flow — for example, unsubscribe them once they’ve done the thing the sequence was asking for.
There is no screen listing who is subscribed, and no way to remove one contact by hand. Plan the way out when you plan the way in.

​
Troubleshooting

A sequence does nothing on its own. Check that a published flow — on the same channel — has a Sequence step pointing at it, and that the sequence’s switch is on Active.
Almost always the window. On WhatsApp, Facebook, Instagram and TikTok a free-form step only reaches a contact who has messaged you recently; when they haven’t, DMLY holds it and retries for about two days, then stops that contact’s run. Contacts who keep replying get the whole sequence; contacts who go quiet don’t.On WhatsApp, build the later steps from approved templates and they arrive regardless. Elsewhere, shorten the run and give each step a reason to reply.
Templates are a WhatsApp thing. Facebook and Instagram have a Send as picker, but it offers Standard send and Human agent — no templates. On Telegram, SMS, Live Chat and TikTok there’s no picker at all: a step is free-form text.On a WhatsApp channel, set Send as to Utility template or Marketing message. If the picker is empty, you have no approved template in that category yet — Manage templates takes you to submit one. See message templates.
A step that had to be held and retried is rescheduled about an hour later without re-checking From and To. The hours are applied when a step is first scheduled, so a step that waited on a closed window can land outside its usual times. Remember the hours are UTC, too.
Active sequences on the Overview counts contacts currently working through a sequence, not sequences. Twelve means twelve contacts mid-run.
Nothing breaks loudly, which is the problem. The flow keeps running and the Sequence step just does nothing — that’s what Flows that subscribe to it will need a new target means on the delete prompt. Open each flow that used it and point the step at a new sequence, or remove the step.
