InstantDM vs ReplyRush
ReplyRush is one of the cheapest ways into Instagram and Facebook DM automation: a free tier with 1,500 DMs a month, paid plans from $10, and both platforms covered on every tier. The trade is meters. Every plan caps your monthly DMs, your DMs carry ReplyRush branding until the $25 plan, and contact data is retained for 30 to 365 days depending on tier — your list is on a clock. InstantDM is $9.99/month flat: unlimited DMs under your own name, the AI agent included, and a contact list that stays yours.
Official Meta Business Partner · Updated August 2026 
What is InstantDM?
InstantDM is an Instagram comment and DM automation platform for creators, shops, and businesses, on web, iOS, Android, and Shopify. It's an official Meta Business Partner on the official Instagram Graph API. Pricing is flat: Legend Pro at $9.99/month and Trendsetter at $24.99/month, both with unlimited contacts, plus a forever-free plan of 500 automations a month. The AI agent is included without credit metering: set a goal, like qualifying leads or booking calls, and it works to achieve it. Four safety controls (DM Queue, Super Slow Mode, Rate Limit Controller, Flood Control) run on every plan.
What is ReplyRush?
ReplyRush is an Instagram and Facebook DM automation tool built around comment-to-DM triggers on posts, Reels, and stories, with follow-up DMs, email capture, sponsored-post auto-replies, and a web dashboard plus iOS and Android apps. It runs on Meta's official APIs and advertises official Meta Business Partner status, citing 41,000+ creators and brands. Pricing is tiered by volume: Free with 1,500 DMs a month, Lite at $10 for 7,500, Boost at $25 for 40,000 across 3 Instagram and 3 Facebook accounts, and Max at $100 for 400,000. Branding removal starts at Boost, and contact data is retained for 30 to 365 days by plan. (As of August 2026, per replyrush.com.)
Why heavy users pick InstantDM
No monthly DM meter.
$9.99/month with unlimited DMs and contacts. On ReplyRush, one Reel that takes off can burn through a 7,500-DM Lite cap in a weekend; InstantDM doesn't count.
Your DMs, your name, from day one.
ReplyRush stamps its branding on automated DMs until you pay for Boost at $25 ("Remove App Branding" is a Boost feature). InstantDM never adds branding, even on the free plan.
Your contact data isn't on a timer.
ReplyRush retains data for 30 days on Free, 180 on Lite and Boost, and 365 on Max, per its pricing page. InstantDM keeps your contacts, unlimited, for as long as your account exists.
A real AI agent, included flat.
ReplyRush's AI generates triggers and auto-replies. InstantDM includes a goal-based agent that works toward qualifying leads, booking calls, or selling — with no credit metering.

Switching from ReplyRush to InstantDM
Instagram's API doesn't allow any tool (ReplyRush, InstantDM, or anyone else) to import DM contacts from another platform. Before you leave, export any collected emails from ReplyRush: its 30-to-365-day retention windows mean older records may already have aged out. The rebuild itself is quick. Your keyword triggers recreate in minutes in the flow editor, and your contact list refills as people comment and message. On InstantDM those contacts are unlimited on every plan and never expire, so run the free plan side by side with ReplyRush until you're confident.
Which one should you pick?
Choose InstantDM if…
- Your volume is real or spiky, and a viral Reel shouldn't push you into a $100 tier
- You want DMs sent under your own name from day one, with no branding on any plan
- Your contact list is an asset you keep, not data on a 30-to-365-day clock
- You want a goal-based AI agent included flat, not just AI-generated triggers
- You sell on Shopify or build on the API (available from the free trial)
Choose ReplyRush if…
- You want the cheapest possible start and 1,500 free DMs a month covers you
- You run several accounts: Boost bundles 3 Instagram + 3 Facebook for $25
- Facebook coverage on the free tier matters to you
- Simple keyword triggers are enough and you don't need a conversational AI agent
InstantDM vs ReplyRush: common questions
What is the best ReplyRush alternative in 2026?
InstantDM is the closest like-for-like alternative: comment-to-DM, story replies, and Facebook automation like ReplyRush, but with no monthly DM caps or branding stamps, a goal-based AI agent included, and contacts that are unlimited and kept with no retention window. ReplyRush's lane is cheap tiered pricing and multi-account bundles; InstantDM's is flat pricing at $9.99/mo that ignores volume.
How much does ReplyRush cost in 2026?
Four tiers, priced by DM volume: Free with 1,500 DMs a month, Lite at $10 for 7,500, Boost at $25 for 40,000 with 3 Instagram and 3 Facebook accounts, and Max at $100 for 400,000 with 5 of each. Branding removal starts at Boost, and contact data is retained for 30 to 365 days depending on plan. (As of August 2026, per replyrush.com/pricing; check the live page.)
Does ReplyRush have a free plan?
It does, and it's genuinely usable: 1,500 DMs a month on 1 Instagram and 1 Facebook account. The gates: DMs carry ReplyRush branding, there's no public comment auto-reply or email capture, and contact data is kept for 30 days. InstantDM's free plan is 500 automations a month, forever, with no branding and a 7-day trial of paid features.
Does ReplyRush put branding on your DMs?
On Free and Lite, yes. "Remove App Branding" is listed as a Boost ($25/mo) feature on the ReplyRush pricing page, so automated DMs on the lower tiers carry ReplyRush branding. InstantDM never adds branding to your DMs, on any plan including free.
Does ReplyRush have an AI agent?
Not a conversational one. ReplyRush advertises AI-generated triggers and AI-assisted inbox auto-replies, and its own comparison content concedes it isn't a conversational AI agent. InstantDM includes a goal-based AI agent: set a goal (qualify leads, book calls, answer FAQs, sell) and it works toward it in conversation, with no credit metering.
Is ReplyRush safe to use?
Both tools run on Meta's official APIs. ReplyRush advertises official Meta Business Partner status and a DM queue from its Lite plan up. InstantDM is an official Meta Business Partner using OAuth, so it never asks for your password, and it runs four safety controls (DM Queue, Super Slow Mode, Rate Limit Controller, Flood Control) on every plan, including free.
Which is cheaper at high volume?
InstantDM. Its $9.99 and $24.99 plans have no monthly DM cap, so a viral month costs the same as a quiet one. On ReplyRush, volume moves you up tiers: past 7,500 DMs a month you need Boost at $25, past 40,000 you need Max at $100. If you regularly clear 40,000 DMs a month, the comparison is $9.99 versus $100.
How long does ReplyRush keep your contact data?
Its pricing page lists data retention of 30 days on Free, 180 days on Lite and Boost, and 365 days on Max (August 2026). Plan around that if you rely on collected emails or contact history. InstantDM has no retention window: contacts are unlimited on every plan and stay for the life of your account.
