ANSWERS

Frequently Asked Questions

Have questions? We've got answers. If you don't find what you're looking for, feel free to reach out.

What is BuffSend?

BuffSend is an email marketing platform that helps businesses send campaigns, verify emails, and improve deliverability. We focus on campaign execution, tracking, and analytics to help you reach your audience effectively.

How do I get started with BuffSend?

Getting started is simple! Sign up for a free account, connect your email sender (Gmail, Outlook, or SMTP), import your contacts, and launch your first campaign. No credit card required for the free plan.

What are credits and how do they work?

Credits are used for actions such as email verification. Free users get 75 credits monthly, and Growth users get 1,000 credits monthly.

What email senders can I connect?

You can connect Gmail or Google Workspace, Outlook or Office 365, and SMTP senders. Free accounts are limited to one sender connection, and Growth accounts can connect multiple senders. Sender-provider quotas still apply.

Is BuffSend good for high-volume sending?

BuffSend supports higher-volume outreach through connected senders, campaign queues, and sender quotas. Actual sending capacity still depends on your plan, sender-provider limits, domain reputation, list quality, and content practices.

How do automated email sequences work?

Create multi-step email sequences with custom delays between messages. Set up follow-ups, personalize content with variables, and track performance. Unsubscribes, bounces, and suppression checks prevent future steps; replies are tracked for review.

Do you help with deliverability?

We provide deliverability tools including SPF/DKIM/DMARC checkers, spam word analyzers, and authentication setup. However, deliverability success depends on your list quality, content, and sending practices. We offer guides and tools, but not direct consulting services.

Can I import my existing contact lists?

Yes. BuffSend focuses on campaign execution, tracking, and analytics. You can import your own contact lists and use our built-in email verification tools.

How do I target the right audience?

Use your own contact lists and segmentation tags to create targeted campaigns. You can add fields like job title, industry, and location for better targeting.

How does email verification work?

Email verification checks address format, domain validity, MX records, and duplicates. Bulk CSV verification is available for larger lists, with results you can review before using contacts in campaigns.

Can I search for companies specifically?

Yes. Manage companies by domain, industry, location, size, and keywords. Keep company profiles, contacts, and campaign activity linked so account-level context stays organized.

Are your free email tools really free?

Yes. The SPF checker, DKIM checker, DMARC checker, spam word analyzer, subject line tester, preview simulator, template gallery, and related tools are available without signup.

What if I need help getting started?

Use the knowledge base and email support to get started. Growth users get priority support for account, billing, and platform questions.

How does BuffSend handle sender reliability?

Campaign sending checks sender connection status and sender quotas. If a sender hits its provider limit or needs attention, campaigns can be throttled, rescheduled, or moved to another available sender when configured.

Are there any sending limits?

The Free plan includes 100 emails per month. The Growth plan has no monthly email cap in BuffSend, but sender-provider limits, sender reputation, and safe sending practices still apply.

What contact data can I store?

Contact records can store email, name, company, company domain, job title, phone, LinkedIn URL, location, group, tags, lifecycle status, lead status, notes, and custom fields.

Can I pause or stop campaigns?

Yes! Pause campaigns anytime and resume later. Stop individual sequences or entire campaigns instantly. Edit running campaigns to update content, change timing, or modify recipient lists. All changes take effect immediately.

Can I customize email templates?

Yes. Campaign emails use a rich text editor and template variables, so you can write and format sequence steps, preview personalized output, and reuse template content.

What happens to my data if I cancel?

You can export contact data before canceling. Existing account access and data retention follow the current billing state and the terms of service.

What does the spam word analyzer check?

Our spam analyzer scans your email content for 500+ spam trigger words and phrases. It provides a spam risk score and highlights problematic terms that might trigger spam filters. Get suggestions for alternative wording to improve deliverability.

What happens after the free plan limits are reached?

The Free Plan is designed to give you a great start. If you exceed the monthly limits, campaign sending and credit-based actions for that month will pause. You'll still have access to your existing data and contacts. To continue with higher limits, you can upgrade to our Premium Plan at any time.

Can I change plans anytime?

You can manage billing from your account and switch plans when available. Plan changes update your monthly limits and credit allocation according to the active subscription.

Do you offer refunds?

Contact support for billing questions. Refund requests are handled according to the current terms of service and the status of the subscription.

How do integrations work?

HubSpot sync is supported for contacts. BuffSend also has provider webhook handlers for bounce and complaint events where those providers are configured.

What CRM integrations do you support?

HubSpot is the active CRM integration. You can also import and export contacts with CSV. Pipedrive, Zoho, and Zapier are shown as planned integrations, not active homepage promises.

Can I import/export data?

Yes. Import contacts by CSV, import unsubscribed contacts, sync HubSpot contacts, and export contact lists in CSV format.

How do webhooks work?

Provider webhooks can process bounce and complaint events for services such as Mailgun, SendGrid, Postmark, Amazon SES, and Gmail where configured. Opens and clicks are tracked through BuffSend tracking links and pixels.

What analytics and reports are available?

Track sent, delivered where available, opened, clicked, replied, bounced, and unsubscribed activity. Campaign views show rates and contact-level activity for performance review.

Can I track email opens and clicks?

Yes. Opens are tracked with a tracking pixel, and clicks are tracked through redirect links. BuffSend records timestamps, counts, contacts, campaigns, and clicked URLs.

Is my data secure and private?

BuffSend uses account authentication, provider OAuth where available, stored sender credentials for connected accounts, unsubscribe handling, and privacy/legal policies for user data. You remain responsible for lawful list use and consent.

How do you handle unsubscribes and bounces?

Unsubscribes are processed automatically with one-click links in every email. Bounces are tracked and hard bounces are automatically removed from future campaigns. We maintain suppression lists to ensure compliance and protect your sender reputation.

Can I personalize my emails?

Yes. Use template variables such as first name, company, job title, and other contact fields in subjects and email body content. Preview personalization before launching a campaign.

What time zones are supported for scheduling?

Campaign scheduling supports standard IANA time zones and sending windows. The free send-time calculator can help plan send windows before you schedule a campaign.

Do you offer A/B testing?

Growth includes A/B variant support where enabled. Use campaign variant controls and campaign stats to compare performance.

Is there a mobile app?

Our web platform is fully responsive and works on mobile devices. While we don't have a dedicated mobile app yet, the mobile experience includes campaign management, contacts, analytics, and sender tools.

Can I collaborate with team members?

Self-serve team permissions are not presented as a current homepage feature. Contact support if you need multi-user account access.
