A lead magnet
A guide, a checklist, a template. People comment GUIDE, get the PDF in their DMs, and a conversation starts.
A promo code
Post the offer, ask for a keyword, send the code in private. It doesn’t sit in the comments for anyone to copy.
A product link
“Link?” shows up under every Reel. Answer everyone at once with the product page, a size guide or a booking link.
One price, whatever the volume
Comment-to-DM is included from Standard (29 €/month). You don’t pay more when a post takes off.
Instagram and Facebook
DMs go out on Instagram and Messenger. On TikTok and YouTube, Blabla can still reply to comments, but not in private.
Meta’s rules, built in
One private reply per comment, within 7 days. Blabla sticks to these limits so your account stays in good standing.
A history of every send
Each automation keeps a log of its runs: who commented, what went out, what was skipped.
One or several words, like LINK, GUIDE or PROMO.
On one post or on all of them.
Upper or lower case doesn’t matter.
Blabla answers the comment so others see it works.
Several wordings, so replies don’t look copy-pasted.
People reading the thread see that asking pays off.
Write the message once, with a link or a button.
It reaches the person in a few seconds.
Their answer lands in your Blabla inbox, next to their comment.
| Limit | What it means for you |
|---|---|
| Instagram and Facebook only | Works on Instagram professional accounts and Facebook Pages (Messenger). No DM on TikTok or YouTube: their APIs don’t allow it. |
| 1 private reply per comment | Meta lets you send one private message per comment. The conversation goes on once the person answers. |
| 7-day window | The private reply must go out within 7 days of the comment. Older comments can’t trigger it. |
| Top-level comments | Automations watch comments posted under the post, not replies inside a thread. |
| Follow-ups within 24 hours | After the person replies, your next messages follow Meta’s 24-hour messaging window. |
| Tool | How it’s priced | First paid plan |
|---|---|---|
| Blabla | Per workspace, team included, no price per contact | 29 €/month (19 € billed yearly), excl. VAT |
| ManyChat | By active contacts per month, extra contacts billed | $17/month (Essential, 250 contacts) |

Comment-to-DM: your questions
How do I send an automatic DM when someone comments on Instagram?
Connect your Instagram professional account to Blabla, create a comment-to-DM automation, pick a keyword and write the message with your link. When someone comments that word, Blabla replies under the comment and sends the DM within seconds.
Does comment-to-DM work on Facebook?
Yes. On a Facebook Page, the message goes out through Messenger. One automation can cover both your Instagram account and your Facebook Page.
Can I send a DM on TikTok or YouTube?
No. TikTok and YouTube don’t give apps access to private messages. Blabla can reply to comments on those networks, but the DM part only works on Instagram and Facebook.
Why is there only one private message per comment?
It’s a Meta rule: a business can send one private reply per comment, within 7 days of the comment. Once the person answers, the conversation can go on.
How much does comment-to-DM cost with Blabla?
It’s included from the Standard plan, at 29 € a month or 19 € a month billed yearly, excluding VAT, per workspace with the whole team. There’s no price per contact. You can try it free for 7 days, no card needed.
