ManyChat's free plan had 1,000 active contacts from 2018 to early 2026. In March 2026 that number dropped to 25. A creator with 200 followers who comment on a single Reel campaign now hits the cap in the first hour.
That change sent a lot of creators looking for free alternatives. This post tests the actual free plans of the five tools that offer them — what they include, what the real limit is, and which one makes the most sense depending on how you use Instagram.
What Changed With ManyChat's Free Plan
ManyChat's original free plan was genuinely usable. 1,000 active contacts covered most small creators for basic comment-to-DM campaigns. The March 2026 cut to 25 contacts changed that completely.
Under ManyChat's billing definition, an "active contact" is any person who has sent or received a message through your automation in the last 90 days. On a campaign with even modest reach, 25 contacts is exhausted within the first few comments. Any participant after the 25th receives nothing.
The full mechanics of how ManyChat counts active contacts — including why the count does not reset after a campaign ends — are explained in the ManyChat active contacts breakdown. For most creators, the conclusion is simple: ManyChat's free plan is no longer suitable for running real campaigns.
The Five Tools With Usable Free Plans
InstantDM — 1,500 automation runs/month
InstantDM's free plan is the most generous by volume. 1,500 automation runs per month means a creator can respond to 1,500 keyword comments before hitting the cap. For a Reel that gets 300-500 comments, that covers three to five full campaigns per month before needing to upgrade.
What's included: Comment-to-DM, story reply automation, keyword triggers, basic analytics, and direct link delivery. InstantDM is a Meta Business Partner, which means it connects via the official Instagram Graph API — no third-party workarounds, no terms of service risk.
The cap: Once you hit 1,500 runs, automation pauses until the next month. There is no overage option on the free plan — you either upgrade or wait.
Who it's best for: Creators who post frequently and want to test automation across multiple pieces of content before committing to a monthly subscription. The 1,500 run limit is high enough to cover several campaigns per month on a mid-sized account.
LinkDM — 1,000 DMs/month
LinkDM has been building Instagram DM tools since 2016 and now has 49,000+ creators on the platform. Its free plan covers 1,000 automated DMs per month, which is the second-largest free tier in this comparison.
What's included: Comment-to-DM triggers, welcome messages, link delivery, and basic analytics. The platform is specifically built for Instagram — no multi-channel complexity.
The cap: LinkDM queues excess DMs rather than dropping them. If you send 1,200 DMs in a month, the first 1,000 are delivered immediately and the remaining 200 are sent at the start of the following month. This is a meaningful difference from tools that simply stop — participants eventually get the DM, just delayed.
Who it's best for: Creators with a consistent posting schedule who want a stable free tier and do not need advanced giveaway mechanics like leaderboards or referral tracking.
CreatorFlow — 500 DMs/month, all features
CreatorFlow's free plan has the lowest DM cap in this list at 500 per month, but it is the only free plan that includes all features — not a limited subset. Comment-to-DM, follow gating, keyword split testing, CRM segmentation, and story reply automation are all available on the free tier.
What's included: Everything CreatorFlow offers, limited to 500 DMs per month. For testing whether the full automation flow works for your audience before paying $15/month, this is the most useful free plan in the comparison.
The cap: Hard stop at 500. CreatorFlow notifies you at 400 DMs so you have warning before the cutoff.
Who it's best for: Creators who want to fully evaluate a tool's feature set before upgrading, or those whose campaigns consistently stay under 500 DMs per month (smaller accounts, niche audiences with lower comment volume). The CreatorFlow vs ManyChat comparison covers what changes when you upgrade to the paid plan.
ReplyKaro — Free Forever plan
ReplyKaro's Free Forever plan does not publish a hard DM cap — it positions the plan as permanently free for basic use, with paid plans unlocking higher volume and features like multi-account management. The paid plan starts at ₹99/month (roughly $1.20) with UPI payment, making it the lowest-cost paid option of any tool in this list.
What's included: Comment-to-DM automation, keyword triggers, and basic analytics. ReplyKaro is one of the few tools with Hinglish keyword detection — useful for Indian creators whose audiences type in mixed Hindi-English.
The cap: Not publicly specified. The Free Forever plan is designed as a permanent entry point rather than a trial, which makes it useful for low-volume creators who never plan to upgrade.
Who it's best for: Indian creators who want a permanently free tier with UPI as the payment option when upgrading. It is newer than the other tools in this list (368+ creators as of June 2026) and has fewer integrations, but it is the only tool with native India payment support and Hinglish capabilities.
Inrō — Free plan with 50 AI credits
Inrō's free plan is different from the others — it centres on AI conversation credits rather than a DM volume cap. 50 AI credits per month covers basic automation testing. The free plan includes full feature access including comment-to-DM, keyword triggers, and DM sequences.
What's included: All features, limited to 50 AI credits per month. For simple keyword-to-DM flows without AI, the limit is more generous than it sounds — standard automated replies do not consume AI credits.
The cap: 50 AI credits. Once exhausted, AI-powered conversation features pause but standard automation continues.
Who it's best for: Creators interested in testing AI-assisted DM conversations before committing to a paid plan. For pure comment-to-DM automation without AI, the other tools in this list offer higher volume caps.
Side-by-Side Comparison
| Tool | Free DM Limit | Comment-to-DM | Follow Gate | Referral Tracking | UPI Payment |
|---|---|---|---|---|---|
| InstantDM | 1,500 runs/mo | Yes | No | No | No |
| LinkDM | 1,000 DMs/mo | Yes | No | No | No |
| CreatorFlow | 500 DMs/mo | Yes | Yes | No | No |
| ReplyKaro | Not published | Yes | Yes | No | Yes |
| Inrō | 50 AI credits | Yes | No | No | No |
| ManyChat | 25 contacts | Yes | Yes | No | No |
Note: follow gate, referral tracking, and leaderboard features generally require a paid plan on most tools. For a campaign that needs referral mechanics — where participants earn bonus rewards for bringing friends — free plans are typically not sufficient.
What Free Plans Cannot Do
Free tiers cover the basics, but three features are consistently behind a paywall across all tools:
Referral tracking and multi-tier rewards. The mechanics that let participants earn bonus rewards for bringing friends — a referral link, automatic credit counting, and unlocking a second reward tier — are not available on any free plan. If running a viral giveaway with a referral component is the goal, you will need a paid tier.
Email and WhatsApp capture. Collecting an email address or a WhatsApp number inside the DM flow requires a paid plan on most tools. The free plans deliver content and links but do not support lead capture gates.
Analytics beyond basic counts. Free plans typically show you how many DMs were sent. Click-through rates on links, email capture rates, and the full funnel metrics that tell you whether your campaigns are actually converting require paid plans on most tools.
For a creator just starting with automation — testing whether comment-to-DM works for their audience, what keywords drive engagement, what their first-message reply rate looks like — a free plan is genuinely sufficient. For a full campaign with conversion tracking, referral mechanics, and lead capture, free plans run out of functionality before the campaign runs out of potential.
Choosing Between Them
If you want the highest DM volume free, start with InstantDM (1,500 runs). If you want to test a full feature set before paying, use CreatorFlow (500 DMs, all features). If you are an Indian creator who may never want to pay a subscription, ReplyKaro's Free Forever plan with UPI upgrade path is designed for that scenario.
If you eventually outgrow the free tier, the upgrade path matters. The Instagram DM automation pricing comparison breaks down per-contact vs flat-rate vs per-campaign billing, which is the decision that determines your long-term cost as your audience scales.
FAQ
Is there a free Instagram DM automation tool in 2026?
Yes. InstantDM offers 1,500 automation runs per month free. LinkDM offers 1,000 free DMs per month. CreatorFlow gives 500 DMs per month on its free plan with all features included. ReplyKaro has a permanent Free Forever plan. Inrō has a free plan with 50 AI credits. ManyChat's free plan was cut to 25 contacts in March 2026.
Why did ManyChat cut its free plan?
ManyChat reduced its free plan from 1,000 active contacts to 25 in March 2026 as part of a broader pricing restructure. The change made AI features a separate $29/month add-on and tightened active-contact limits across all tiers. The practical effect: any creator with more than 25 campaign participants now needs a paid plan.
Which free Instagram DM automation tool has the highest limit?
InstantDM's free plan offers 1,500 automation runs per month — the highest free tier of any tool in 2026. LinkDM follows with 1,000 free DMs per month. CreatorFlow offers 500 DMs per month but includes all features at the free level, making it the most feature-complete free option.
Can I do comment-to-DM automation for free on Instagram?
Yes. CreatorFlow, LinkDM, InstantDM, and ReplyKaro all support comment-to-DM automation on their free plans. When someone comments a keyword on your post, the tool sends them a DM automatically — no manual work required. The free tiers cap the number of DMs per month, not the features available.
What happens when I hit the DM limit on a free plan?
Most tools stop sending automated DMs once you hit the monthly cap — commenters simply do not receive the automated reply. CreatorFlow and InstantDM notify you when you approach the limit. LinkDM queues excess DMs and sends them at the start of the next month.
UnlockDM's trial gives you a full campaign to test comment-to-DM, follow gating, and referral mechanics without a monthly commitment — you pay per campaign when you are ready to run one, not before.
