Top Gmail Email Sequencers in 2025

Today, we’re comparing: Automagical Nudge vs Rebump vs CloudHQ

If you regularly send outreach, follow-ups, or nurture sequences from Gmail, a good email sequencer (also called auto follow-up or “nudging” tool) can save you hours and reduce lost conversations. But which one is right for you?

In this post, I’ll compare three of the leading options in the Gmail ecosystem:

Automagical Nudge
Rebump

What to Look for in an Email Sequencer

Before diving into each tool, here are criteria you should keep top of mind:

Ease of setup / integration with Gmail — ideally minimal friction, native Gmail UI support
Smart logic / conditional branching — e.g. “stop if replied,” branching based on opens/clicks
Template & personalization — merge tags, customizing per step
Limits, pricing & “free tier” usability — how many emails, what constraints, hidden costs
Reliability & deliverability — whether sequences reliably send and don’t trigger spam filters
Transparency & support — good documentation, responsive support, visibility into what’s happening

With those in mind, let’s compare…

Automagical Nudge — RECOMMENDED

Overview & key features

Automagical Nudge (from Automagical Apps) is a Gmail add-on / Chrome extension designed to embed “nudges” (follow-up sequences or reminders) directly into your Gmail experience.

Pros

AI-first – use AI to dynamically generate “Nudge sequences” from existing emails. Also, the Inbox Monitor feature automatically catches things you missed
Nudge any Email – You can attach nudges (sequences or reminders) to inbound or outbound messages (even after sending).
Unlimited Reminders – Set unlimited reminders per message. If no reply, you can nudge again.
Granular Delivery Window – Full customizability of date AND time of delivery, as well as on-the-fly editing of everything before attaching a nudge sequnce
Gmail Mobile app – It works in Gmail mobile app (via add-on) in addition to desktop.
Build into Gmails user interface- No context switching

Cons / caveats

For high-volume mail merge campaigns, it might not scale as cleanly (it’s more oriented to individual threads). You can however “Bulk Nudge.”
The “nudge logic” tends to be simpler than full marketing automation tools
Depending on your subscription, there may be usage caps or “freemium” constraints

Best fit

Ideal if for sales, customer support, and personal use, especially your follow-ups are often reactive (e.g. responding to incoming messages) or you want a tool that you can retroactively attach reminders to conversations. It’s less about broadcasting mass sequences and more about staying responsive and not dropping threads.

Rebump

Overview & key features

Rebump.CC (often just “Rebump”) is built for Gmail users who want to “bump” emails that haven’t gotten replies. It integrates into Gmail (via Chrome extension) and essentially lets you wrap a follow-up or a sequence around any message.

You can:

Create multiple “Bump sequences” (series of follow-ups) and pick one when sending or after sending.
Set intervals (days) and auto-cancel the sequence if a reply arrives.
Compatibility with Gmail’s “schedule send” (via BCC workaround) — you add a special BCC address so Rebump will catch that message when it’s later sent.

Pros

User-friendly: once installed, the workflow lives in your Gmail UI with minimal extra steps
Good control: you can cancel, skip, or personalize follow-ups
Fairly reliable for basic use — many users report success with it
Free Trial available: (Starting at $10 / mo — 14 day free trial)

Cons / caveats

The BCC workaround to make it work with “schedule send” can feel hacky. If you’re on mobile, you have to BCC a Rebump email address to attach the default nudge sequence
Mobile compatibility relies on the BCC method of attaching a Bump sequence
As with all such tools, heavy usage can bump you against Gmail’s sending limits or spam thresholds
Editing, on-the-fly, the templates or dates/times of delivery are not possible. You are using pre-written templates.
Less suited for very high volume campaigns

Best fit

If you’re someone sending moderate outreach or doing client follow-ups and want something that has basic functionality and with minimal learning curve, Rebump is a strong choice. You ideally do not need to edit your templates in messaging or date/time of delivery since these features are unsupported.

CloudHQ — Auto Follow Up for Gmail / Gmail Sequencer

Overview & key features

CloudHQ is better known as a productivity / sync / extension company, but one of their flagship offerings is Auto Follow Up for Gmail (sometimes called Gmail sequencer, auto-follow, etc.).

You can:

Install a Chrome extension that injects “Auto Follow Up” controls directly in your Gmail compose window.
Create auto follow-up campaigns (upload recipient list, define sequences) or attach sequences to individual emails.
Configure templates, set conditions (e.g. stop when recipient replies), track opens/clicks, mail merge support.
Use “Quick Auto Follow-Up” when you don’t want to build a full template — schedule a reminder for a particular message.
Throttle sends so you don’t exceed Gmail’s limits.

In terms of pricing and limits:

The free (basic) plan allows limited emails per month (e.g. 10 or so) and will append a signature / branding.
Premium is ~$14.99/month per user (unlimited sends, removal of signature, extra features)
In their “cloudHQ Gmail auto follow up” subscription page, they note that the free plan allows 100 emails per month; paid removes that cap.

Pros

Very powerful: supports both per-email sequences and mail merge
Good condition logic (stop-if-replied, merge, tracking)
“Quick follow-up” is convenient for ad hoc usage
Integration with Gmail UI makes it feel native
Throttling / pacing helps stay within Gmail limits

Cons / caveats

No mobile support at all
The free plan is quite restrictive (branding, low send cap)
With higher volume, the overhead of campaign setup might feel more complex
Because it’s more “feature-rich,” there might be more learning curve or occasional quirks
Some users report occasional extension or sync bugs with add-ons in Gmail, especially when Gmail updates (this is a general risk for browser extension tools)
Some users online mention occasional issues or feature rollbacks (as with many extension-based tools)

Best fit

If you want the most flexibility between individual follow-ups and larger batch sequences, CloudHQ is compelling. It’s a middleground between the lightweight simplicity of Rebump and full-blown automation systems. For smaller users, the free tier gives a taste; for serious usage, the paid tier is reasonable.

When to Pick Each Option

When deciding between these Gmail tools, the best choice depends heavily on how much control and mobility you require. If you need the ability to customize your message and delivery time on the fly, Automagical Nudge is the superior option because it allows for granular edits right before sending. It is also the standout winner for mobile users. While Rebump requires a clumsy BCC workaround to function on mobile, Automagical Nudge offers a native experience directly inside the Gmail app.

CloudHQ Auto Follow Up is a viable alternative for users who need to combine batch campaigns with individual reminders, provided they are comfortable with a steeper learning curve and do not need mobile access. However, for professionals who want a tool that “just works” with minimal fuss while still offering advanced features like responding to inbound messages, Automagical Nudge delivers the most seamless experience.

Tips for Better Results (Regardless of Tool)

Regardless of which software you choose, following email best practices is essential to ensure your follow-ups land in the primary inbox rather than the spam folder. You should always include a clear way for recipients to opt out, especially during cold outreach, to protect your domain reputation. It is also critical to space your sequences realistically, allowing two to five days between messages so you do not appear aggressive or spammy.

To maintain a professional image, aggressive use of the “stop on reply” conditional logic is non-negotiable, as sending a pre-written nudge after a client has already responded can kill a deal. Finally, take advantage of personalization features. Even small touches like using the recipient’s first name or referencing a prior interaction can significantly boost engagement. Tools like Automagical Nudge make this easier by allowing you to edit these details instantly before the sequence launches.

Final Verdict: The Best Gmail Sequencer in 2025

After comparing the leading options in the Gmail ecosystem, Automagical Nudge stands out as the best email sequencer for most professionals. It offers the most generous free plan and a robust feature set that includes AI-drafted nudges and an Inbox Monitor, capabilities that competitors like Rebump and CloudHQ simply lack.

While Rebump is a decent option for those seeking extreme simplicity and CloudHQ serves users needing complex batch operations, neither offers the modern, flexible workflow provided by Automagical Nudge. If your goal is to manage conversations efficiently from both your desktop and mobile device without getting bogged down in complex configurations, Automagical Nudge is the clear winner 🏆.
