About MassMutual
Massachusetts Mutual Life Insurance Company, commonly known as MassMutual, is a mutual life insurance and financial-services company headquartered in Springfield, Massachusetts. The company provides life insurance, disability income insurance, annuities, retirement solutions, investments, wealth-management services, institutional solutions, and other financial products designed to help individuals, families, businesses, and institutions manage long-term financial risk and wealth. (massmutual.com)
MassMutual was founded on May 15, 1851, in Springfield, Massachusetts. In 2026, the company celebrated its 175th anniversary. Unlike a publicly traded insurer, MassMutual is structured as a mutual company, meaning eligible participating policyowners have an economic interest in the company rather than outside public shareholders. MassMutual currently serves more than four million customers and policyowners. (massmutual.com)
MassMutual remains one of the largest U.S. life insurers. For 2025, the company reported approximately $3.9 billion in operating earnings, more than $43 billion in sales, nearly $1.1 trillion of life insurance protection in force, and more than $584 billion in assets under management. Roger W. Crandall serves as Chairman, President and Chief Executive Officer. (massmutual.com)

MassMutual Products & Services
MassMutual offers insurance, retirement, investment, and wealth-management products for individuals, families, business owners, institutions, and employers.
Whole Life Insurance
Whole life insurance is one of MassMutual’s core products. It provides permanent life insurance protection, builds cash value over time, and eligible participating policies may receive dividends when declared by the company.
MassMutual has historically maintained a large participating whole-life business and remains a major provider in this category.
Term Life Insurance
MassMutual offers term life insurance designed to provide death-benefit protection for a specified period.
Term insurance can be appropriate for temporary coverage needs such as income replacement, mortgage protection, family protection, or business obligations.
Universal Life Insurance
Universal life insurance provides permanent insurance protection with flexible premium and policy-value features.
Available products and policy structures can vary depending on financial objectives, underwriting, and state availability.
Variable Universal Life Insurance
Variable universal life combines permanent life coverage with investment-linked policy-value options.
Policy values can rise or fall based on selected investment options, making this type of insurance more complex than traditional whole life.
Disability Income Insurance
MassMutual provides disability income insurance designed to replace a portion of income when a qualifying disability prevents the insured from working.
Individual and business-related disability solutions are available through MassMutual financial professionals.
Deferred Fixed Annuities
Deferred fixed annuities are designed to provide tax-deferred accumulation with a guaranteed fixed interest rate during specified periods.
These products can help customers build assets for retirement while protecting principal subject to contract terms. (massmutual.com)
Variable Annuities
Variable annuities allow customers to allocate assets among investment options while receiving tax-deferred growth potential.
MassMutual Envision is one of the company’s current variable annuity platforms and includes optional lifetime-income features. (massmutual.com)
Fixed Index Annuities
Fixed index annuities provide earning potential tied in part to the performance of a market index while offering contractual downside protection.
Products may be available through MassMutual and affiliated businesses.
Immediate Income Annuities
Immediate income annuities convert a premium into a predictable income stream that can begin soon after the contract is issued.
Income options can be structured for a specific period or for life depending on the selected contract. (massmutual.com)
Deferred Income Annuities
Deferred income annuities allow customers to purchase guaranteed future income beginning at a later date.
These products are often used as part of a retirement-income strategy.

How to File a Complaint Against MassMutual
Customers may need to file a complaint involving a policy, billing, claim, annuity, account access, financial professional, beneficiary change, cancellation, privacy issue, retirement product, or another MassMutual service. Keep your policy or account number, correspondence, statements, payment records, representative names, and previous case information before escalating.
Step 1: Contact MassMutual Customer Service
Begin by calling 1-800-272-2216 and explain the issue clearly. Provide the policy number, account details, relevant dates, and the resolution you are requesting. If the issue involves a specific financial professional, identify that person and describe any prior discussions. Ask the representative to document the complaint and provide a case or reference number where available. Keep detailed notes of the call. (massmutual.com)
Step 2: Contact Your Financial Professional or Specialized Team
If the issue involves insurance recommendations, policy servicing, retirement planning, investments, or another advisor-supported product, contact your MassMutual financial professional. For digital-account issues, use 1-800-775-4331. For retirement-plan servicing, certain plans use 1-800-743-5274. Using the correct department helps ensure the complaint reaches staff with access to the relevant records.
Step 3: Request Supervisor or Formal Internal Review
If the issue remains unresolved, contact the Service Center again and request supervisor or management review. Provide the original complaint history, prior reference numbers, copies of statements or forms, and the exact outcome you are seeking. Complaints involving financial products can require review by compliance, claims, underwriting, annuity, investment, or legal personnel depending on the issue.
Step 4: Send Formal Written Correspondence to MassMutual Headquarters
For a serious unresolved complaint, send written correspondence to Massachusetts Mutual Life Insurance Company, 1295 State Street, Springfield, MA 01111-0001. Include your full name, contact information, policy or account number, relevant dates, earlier case numbers, and a clear chronology of the dispute. Attach copies rather than original documents and keep proof of delivery. (massmutual.com)
Step 5: Contact the Appropriate External Regulator if Necessary
The appropriate external authority depends on the product and complaint. Insurance complaints can usually be submitted to the insurance department in the state where the policyowner resides. Securities and investment complaints may involve FINRA or the SEC when a registered securities product or representative is involved. Privacy concerns may involve state or federal privacy regulators. Customers should retain all policy documents, statements, complaint records, and MassMutual responses before escalating externally.
