## InboxPro

InboxPro works inside the inbox you already use rather than asking you to migrate to a new one. You connect a Gmail or Microsoft account, import contacts, and then use the extension to generate or summarise emails with AI, personalise messages with merge tags, and schedule multi-step follow-up sequences that pause or continue based on whether a prospect replies. A built-in calendar gives prospects a public booking page that syncs with Google, Office 365, Outlook, and iCloud, so scheduling happens without the usual back-and-forth.

The tracking layer is what turns the mailbox into a reporting surface: open and link-click notifications arrive in real time, and the analytics dashboard breaks down sent and received volume, busiest hours, and best-performing messages. Templates, a signature builder, an email checker, and optional Zoom integration round out the feature set, and contacts can be synced or exported as CSV at any point.

The pricing ladder is deliberately generous at the bottom: a free forever plan covers one user and 250 emails a month, while paid tiers scale users, mailboxes, monthly email volume, and the daily AI email allowance. Teams that need more seats, custom volumes, or advanced training can request custom pricing.

**Pricing & Plans:** Free forever plan (1 user, 250 emails/month). Paid tiers billed yearly: Basic about $10/mo, Professional about $25/mo (3 users), Growth about $50/mo (5 users), plus custom enterprise pricing on request. Annual billing saves up to 25%.

- **AI email assistant:** Compose or summarise messages from a subject line, keywords, and a chosen tone of voice; daily AI email allowances scale from limited on Free to 200 per day on Growth.
- **Follow-up sequences:** Build multi-step email sequences with triggers and conditions, start or stop them at will, and cap them at one sequence on Free or unlimited on paid plans.
- **Built-in booking calendar:** Publish a public scheduling page connected to Google, Office 365, Outlook, and iCloud calendars, with notification handling and no double-booking.
- **Tracking and analytics:** Get real-time open and link-click notifications plus weekly and monthly reports covering email volume, top-performing messages, and busy hours.
- **Templates, merge tags, and signatures:** Save reusable templates, personalise each message with contact fields, and attach a professionally designed signature with your photo and details.

**Strengths:** Works inside Gmail and Microsoft accounts, so there is no inbox migration; Free plan is genuinely usable, with paid tiers starting around $10/month; Combines AI writing, sequences, scheduling, tracking, and signatures in one subscription; Templates, merge tags, analytics, and calendar pages are all included rather than sold as add-ons

**Limitations:** AI email generation is capped by a daily quota that varies by plan; The lowest free tier limits you to a single sequence and one mailbox; Advanced CRM-level reporting and pipeline management are not the focus

## Robly Email Marketing

Robly is a US-built email marketing service aimed squarely at small businesses, nonprofits and local organizations that want strong deliverability without enterprise complexity. Its core pitch is engagement: OpenGen automatically resends a campaign to subscribers who skipped it the first time, Robly AI picks the optimal delivery time per subscriber, and Robly Engage lets you target and prune non-openers. Together these features are marketed as an open-rate lift of up to 50%.

The platform covers the full campaign workflow. You build emails from mobile-responsive templates or a custom-designed template, segment your list with behavioral and tag-based logic, set up autoresponders and automated journeys, and grow your audience with exit-intent popups, embedded forms and landing pages. Real-time reporting and A/B testing round out the toolkit, and an open API plus integrations with tools like Shopify, WordPress, Zapier and Segment connect Robly to the rest of your stack.

Pricing is contact-tiered on a monthly or annual billing cycle, starting around $19/month for up to 500 contacts, with SMS sold as an add-on rather than a standalone product. Every plan begins with a 14-day free trial. Robly positions itself as a lower-cost alternative to Mailchimp and Constant Contact, and leans heavily on phone, chat and email support from a US-based team as a differentiator.

**Pricing & Plans:** 14-day free trial, then contact-tiered subscriptions billed monthly or annually. Entry tier is about $19/month (or $15/month annual) for up to 500 contacts, rising through tiers for 501-2.5k, 2.5k-5k and larger lists. SMS is an optional paid add-on to an active email plan. Custom templates from $99.

- **Robly OpenGen:** Automatically resends an email to subscribers who did not open the first version, giving each campaign a second chance to land in the inbox.
- **Robly AI send timing:** Analyzes subscriber behavior to deliver each campaign at the moment an individual contact is most likely to open it.
- **List growth and popups:** Exit-intent popups, timed widgets, embedded forms, Facebook sign-up tabs and landing pages designed to convert visitors into subscribers.
- **Automations and autoresponders:** Multi-step email journeys and drip campaigns triggered by subscriber behavior, so follow-ups go out at the right moment without manual work.
- **Segmentation, A/B testing and reporting:** Build granular segments with AND/OR logic, tags and engagement data, split-test campaigns, and track opens, clicks and revenue in real time.

**Strengths:** OpenGen resends and AI send-time optimization directly target open rates; Straightforward, contact-tiered pricing that undercuts many big-name competitors; Strong list-growth toolkit with exit-intent popups, forms and landing pages; Responsive US-based phone, chat and email support highlighted by long-term users

**Limitations:** SMS requires an active email subscription and cannot be bought standalone; Feature depth in automation and analytics trails some enterprise-grade rivals; Custom template design is a separate paid service rather than included
