What stands out most for me is the automation and workflows. HubSpot makes it incredibly easy to set up lead nurturing sequences, automate follow-ups, and segment contacts based on behavior - all without needing deep technical knowledge. The integration with the CRM ensures every campaign action ties directly to sales outcomes, which is a huge plus for tracking performance. Review collected by and hosted on G2.com.

lemlist offers a large set of features to control all the process of email outreach.
Also listed in AI Sales Assistant, Email Deliverability, Outbound Call Tracking, Email Marketing

The multichannel sequencing is the real thing: email and LinkedIn steps live in the same cadence, so a prospect flow isn't stitched together across three tools. The personalization variables let me make every message feel one-to-one instead of one-to-thousand, which is where reply rates actually move. Deliverability tooling (warmup, sending limits, inbox rotation) is baked in rather than sold as a separate product, and that has kept my domains healthy through sustained sending. The API and integrations are solid enough to plug into the rest of my stack instead of forcing me to work inside their UI all day. Support and the community content are genuinely useful when you're debugging a setup. Review collected by and hosted on G2.com.
Whether you’re looking to reach more customers, sell more products, or simply share your passion with the world, Constant Contact has all the tools, features, and expert guida
Also listed in Email Deliverability, Email Template Builder, SMS Marketing, Social Media Management, Event Marketing

I use Constant Contact to communicate with 534 employees across 4 states. I love that it prevents us from missing anyone in our company by allowing us to upload CSV files of employee contact information. I really enjoy the ability to upload flyers and designs we've already created, and it's awesome that I can also create communications from scratch. Plus, the ability to store photos and data such as company headshots and signatures is really helpful. This means we can digitally "sign" communications with a specific executive's saved signature and include their photo, which is pretty neat. Implementation was extremely easy, and now we have several Constant Contact accounts used within our company. Overall, the ease of use and the flexibility in managing our communications stand out as top features. Review collected by and hosted on G2.com.
ActiveCampaign offers effortless email and marketing automation. Grow your business with AI-powered automations that suggest, personalize, and validate your marketing campaign

I’m Monica Hale, Multi-Client Outsourced Bookkeeping & International Accounting Specialist at Dallas Cross-Border Accounting Partners, a 78-person virtual accounting firm in Dallas, Texas. I manage our client communications and workflow reminders using ActiveCampaign, while administering Clearbooks for our US cross-border trade clients. I rely on its user group controls, webhook integrations and contact audit logs to coordinate client document requests, tax deadline follow-ups, and manage client PII under CCPA guidelines.
My favorite feature is the full-featured settings sidebar paired with granular Users and Groups permission controls, which cuts roughly 6 hours each week spent managing team access, organizing client contact records, and scheduling recurring accounting follow-up emails. The left-hand navigation panel puts Account, Security, Integrations, Manage Data and Import/Export Status all in one place, so I can quickly adjust user permissions, review webhook connections, or clean contact data without jumping between separate tools. The account settings page centralizes our core account identifiers and team profile information, and Gravatar sync keeps our team member profiles consistent with minimal manual maintenance. This unified admin workspace is incredibly valuable during our busy quarterly tax preparation cycles.
The contact automation and integration tools are my daily workhorses for multi-client accounting workflows. I build segmented contact groups separated by client entity, tax filing type and cross-border vendor status. I connect ActiveCampaign to Clearbooks and QuickBooks Online using Zapier webhooks; when a new invoice or overdue AP bill appears in Clearbooks, ActiveCampaign automatically triggers a personalized email requesting receipts, bank statements or supporting financial documents from our clients. I also set up automated reminder sequences for upcoming tax deadlines, year-end bookkeeping handoffs, and cross-border VAT documentation requests. The platform’s activity log tracks every email sent to each client, creating a clear immutable trail of communications, which is critical for our US GAAP audit readiness and CCPA compliance for client business PII.
An unexpected benefit I’ve discovered is how ActiveCampaign’s permission grouping helps me protect sensitive client financial data. I can create limited-access groups for junior bookkeeping staff; they can view assigned client communication threads and send document reminders, but cannot export full contact databases. Last quarter during our busiest tax season, I built separate automation workflows for UK-US cross-border clients and domestic US businesses. I used the import/export tools to cleanse duplicate client contacts before launching reminder campaigns, and verified webhook health from the integrations menu to ensure transaction alerts flowed correctly between our accounting stack and ActiveCampaign. The platform also maintains contact opt-out preferences, so clients can unsubscribe from non-essential reminders, which simplifies our CCPA privacy governance. Every client outreach event is logged, giving me audit-ready evidence for our privacy and tax reviews.
Suggestions for the product team: Build native connectors for Clearbooks, QuickBooks Online and tax preparation software to eliminate Zapier webhook dependency. Add finer export restrictions so junior team members cannot download full datasets containing sensitive client financial PII. Expand audit logging to capture automation edits and contact list changes for compliance reviews. Add pre-built accounting templates for tax deadline reminders, receipt collection and cross-border document requests. Improve duplicate contact merging to reduce redundant client profiles when importing accounting data. Overall, ActiveCampaign’s flexible automation, strong user access controls and centralized admin panel streamline our multi-client accounting outreach and help us maintain CCPA and US GAAP-ready communication records for our cross-border trade clients.

I really appreciate Brevo Marketing Platform for its ability to handle both email and SMS marketing in one place. The platform is very user-friendly, even for our team that's not experienced with email marketing. It's really quick to go from start to finish when creating and sending out email campaigns, and I love how you can schedule them in advance, which makes planning a breeze. Another standout feature for me is how easy it is to duplicate past campaigns and reuse them. It's a massive time-saver as I can make a few tweaks for different target demographics without having to start from scratch each time. Additionally, the pricing is significantly better than our previous service, and the initial setup was very simple with not much setup required. We will use an AI tool like ChatGPT or Claude to write out all of our copy, and then we will easily copy and paste it, put a design together in Brevo, and then be able to distribute just like that.

My clients notice the effort in the emails due to the way I can organize photos, paragraphs, links, and make everything look neat.

I also find the contact history very helpful. When I open a contact, I can see the previous activity and email conversations in one place. Before following up with someone, I can quickly check the earlier communication and get the context without having to search through old emails. Review collected by and hosted on G2.com.

I really enjoy how user-friendly Attentive is. At first, when my company suggested that we dive into integrated SMS marketing to complement our existing Email communications, I eye-rolled at the approaching headache of learning a new program. Fortunately, I was very relieved when I began working with Attentive and realized how straightforward, simple, and user-friendly it is to use alongside and in support of our existing communications and programs, such as Salesforce Marketing Cloud. Given the ROI success and overall performance of this platform, I'd highly recommend Attentive to a fellow colleague. Added bonus: their support team has been communicative and supportive throughout the process. Review collected by and hosted on G2.com.
